Solution:
Q1. SOL: 1
Let the amount of investment with each one be Rs. 400, then Hari lal = [400(1.1)^{2}]
Hari Prasad = [100(1.1)^{2}] + [300 + (300*r*2)/100]
So,
[400(1.1)^{2}] = [100(1.1)^{2}] + [300 + (300*r*2)/100]
R = 10.5 %
Q2. SOL: 2
Interest on 22500 = 0.1 * 22500 = 2250
Charges for managing concern = 60*12 = 720
If yearly profit is X then A & B share = x/2
x/2 – 2250 + 720 = ½(x/2 – 720 +2250)
x = 9180 Rs.
Q3. SOL: 3
Total age of X person initially = 60 X year
Total age of X person finally = 60x – 52  68 + y +72 = 60x +y 48
60x + y – 48 = 61x
Y – 48 = x
As 54 < y < 64, 6< x < 16
As X is a perfect square, x = 9 & y = 57
Q4. SOL: 5
A = ( H+E+P ) / 3 = 70
B = E – H = 10
C = B + P = 120, So marks of phy can’t be determined
Q5. SOL: 2
A = R – Q = 100
B = P = 270
C = Q : R = 3:7
So, A & C are sufficient to answer the question.
Q6. SOL: 1
Let length of train be L, and speed be = m/s
A = L/S = 6
B = (L+L2)/(S10) = 12
C = (L+40)/S = 18
So, we can find speed of train using A & C
Q7. SOL: 4
Q8. SOL: 3
Q.9 SOL: 1
Let ‘x’ be the number of standard bags and ‘y’ be the number of deluxe bags.
Thus, 4x + 5y ≤ 700 and 6x + 10y ≤ 1250
Among the choices, 3 and 4 do not satisfy the second equation.
Choice 2 is eliminated as in order to maximize profits the number of deluxe bags should be higher than the number of standard bags
Q10. SOL: 3
Curved surface area = 22/7 * r * l = 22/7 * 12 * 13 =20
