Tips to crack the written:
1. Read the question from last 2 lines if not able to get go to last 3 lines bottom up approach is more importatnt because saying about (Eg: lilavathi ka hei8 he will ask product of 2 number what are those sum of squares of the same numbers at last) this why read it from last
2. Topics to be concentrated in R.S Aggarwal uncle's book
a) Pipes and cisterns (Only concentrate on methods like simulaneus filling taps and sequentital filling time taken and size of tub )2 problems
b) Time and Distance (Average distance problems formula-2xy/(x+y) x-first speed y-second speed -1 prob and d=s*t simple problem only 1 so total 2 problems
c)Numerical calculations simple problem based on (A+B)^2=A^2+B^2+2AB AND (A+B)^3
But not directly he will ask it using lilavathi story telling the concept at last saying that product of two numbers is something and sum of two numbers is something find sum of squres of that number A+B is given AB is given solve it using A+B whole square formal and get sum of squares 2 problems
d) Ages problems 2 problems
e) Surface area and formulas on geomentry 1 problem
f) Permutation -2 problems
g) Probability -2 problems
h) Blood relations -2 problems same problems from R.S uncle(Aggarwal)
Just know the concept to solve and use the 1st tip its enough you will be able to solve 16 questions 3 puzzles are there which i will be sharing all the types.
a) Uncle puzzle is there which means 7 rupees must be divided between 3 things banan, choco, biscuit for buying this for this type of puzzle answer is always 1. 1st item 2-2nd item1-3rd item squence is 1,2,1
b) My papers as different puzzle that is 20 cake pieces must be divided among 3 people mother father and sons that is mother eats 2 pieces father eats 3 and son eats half so what will be the quantity to so choose the option which suits the question cum from options that is add the qunatity by father and mother and son to get total 20 which will suit it that is the answer.
c) A question on arrangement on letters answers may me one is bird or animal if its repeteka its bird if its rigte its animal (tiger).
d) A question on hand shake which is from shakus puzzle buk formula is 2^n=n(n-1)/2 number of hand shakes problem 8 people attending party number of hanshakes with cycle means 8*7/2=28 or if u find the word no cycle than answer is 7 one less
e) A question on socks to be picked in dark room to get the socks of same color its number of choices total number of types of socks +1
f) A problem on cake preparing toppings its always (ans:ncm=2Cool same as handshakes
g) A problem on buliding number number of 2's or 3's or 4's etc upto 9 answer is always 20 (count 2 in 22 two times every body in this forms will written8 19 its worng its answer is 20 for 2-9 number and 21 for number of 1's because 100 is included.
h) A problem on ohm law V=IR formula simple bit this problems if you prepare its enough to get 30 out of 35 may be 35 also but remaining 3 i don't know how to solve

25) Direction problems. A man goes 50 km North, then turned left walked 40 km, then turned right? In which direction is he in?
Ans: North
Tips to crack the written:
1. Read the question from last 2 lines if not able to get go to last 3 lines bottom up approach is more importatnt because saying about (Eg: lilavathi ka hei8 he will ask product of 2 number what are those sum of squares of the same numbers at last) this why read it from last
2. Topics to be concentrated in R.S Aggarwal uncle's book
a) Pipes and cisterns (Only concentrate on methods like simulaneus filling taps and sequentital filling time taken and size of tub )2 problems
b) Time and Distance (Average distance problems formula-2xy/(x+y) x-first speed y-second speed -1 prob and d=s*t simple problem only 1 so total 2 problems
c)Numerical calculations simple problem based on (A+B)^2=A^2+B^2+2AB AND (A+B)^3
But not directly he will ask it using lilavathi story telling the concept at last saying that product of two numbers is something and sum of two numbers is something find sum of squres of that number A+B is given AB is given solve it using A+B whole square formal and get sum of squares 2 problems
d) Ages problems 2 problems
e) Surface area and formulas on geomentry 1 problem
f) Permutation -2 problems
g) Probability -2 problems
h) Blood relations -2 problems same problems from R.S uncle(Aggarwal)
Just know the concept to solve and use the 1st tip its enough you will be able to solve 16 questions 3 puzzles are there which i will be sharing all the types.
a) Uncle puzzle is there which means 7 rupees must be divided between 3 things banan, choco, biscuit for buying this for this type of puzzle answer is always 1. 1st item 2-2nd item1-3rd item squence is 1,2,1
b) My papers as different puzzle that is 20 cake pieces must be divided among 3 people mother father and sons that is mother eats 2 pieces father eats 3 and son eats half so what will be the quantity to so choose the option which suits the question cum from options that is add the qunatity by father and mother and son to get total 20 which will suit it that is the answer.
c) A question on arrangement on letters answers may me one is bird or animal if its repeteka its bird if its rigte its animal (tiger).
d) A question on hand shake which is from shakus puzzle buk formula is 2^n=n(n-1)/2 number of hand shakes problem 8 people attending party number of hanshakes with cycle means 8*7/2=28 or if u find the word no cycle than answer is 7 one less
e) A question on socks to be picked in dark room to get the socks of same color its number of choices total number of types of socks +1
f) A problem on cake preparing toppings its always (ans:ncm=2Cool same as handshakes
g) A problem on buliding number number of 2's or 3's or 4's etc upto 9 answer is always 20 (count 2 in 22 two times every body in this forms will written8 19 its worng its answer is 20 for 2-9 number and 21 for number of 1's because 100 is included.
h) A problem on ohm law V=IR formula simple bit this problems if you prepare its enough to get 30 out of 35 may be 35 also but remaining 3 i don't know how to solve
