ANSWERS
1. (3)
2. (3)
Profit = (10-9)/9 × 100= 100/9 = 11 1/9%
3. (3)
Let the length and the width be x and y
X . y = A
25% of x = x ×25/100=x/4
New length = x + x/4=5x/4
Let decrement in width be p%
New width = y – yp/100=(100y-yp)/100
5x/4×y(100-p)/100=xy
100 – p = 80
P = 20%
4. (2)
5. (1)nearest squares to 7000 are 83^2 and 84^2 , so taking 84 in consideration
84^2 = 7056, 56 should be added to make 7000 = 7056 which is a perfect square
6. (2)his loss % = 4/36×100= 100/9=111/9%
7. (3)
8. (2)ratio of their investment = 185000 :225000 = 37 : 45
So the profits will be in the same ratio = 37 : 45
Value of 45 parts = 9000 , value of 37 parts = 7400,
Total profit = 9000 + 7400 = Rs 16400
9. (1)x/20=65 ;x=1300
Acc to the question ,
96-69 = 27
New x = 1300 – 27 = 1273
1273/20 = 63.65
10. (5)Rate of compound interest = 12000 (1+5/100)^3- 12000
= Rs 1891.5
(1) 1/2
(2) 2/3
(3) 4/5
(4) 9/10
(5) 6/5
