1.(3) 2.(2) 3.(2) 4. (5) 5.(3) Ratio =24/16= 3 : 2
Solutions (6-10)
6. 3; Both statements are required for answer.
SP = 12000, Profit = 20%
Cost Price = 1000 ie profit = 2000
Total profit = 2000 × 20 = 40000
7. 3; From statement I:
x = 4y …(i)
From statement II:
x – 5 = 7(y – 5)
7y – x = 30 …(ii)
Solving equations (i) and (ii), x = 40, y = 10
8. 5; Data is not sufficient to find the answer.
9. 4; Both statements alone are sufficient to answer.
Let be speed = v, distance = x, time = t
t = x/v …(i)
From statement I:
x/5v/4=t – 20
4x/5v= t – 20
x/v = 5/4(t – 20) …(ii)
From (i) and (ii), t = 5 / 4(t – 20)
4t = 5t – 100
t = 100 seconds
From statement II:
x / v / 2 = t + 100
2x / v = t + 100
t + 100 = 2t
t = 100 seconds
10. 3; Both statements are required to answer the question.
From statement I:
1/v = 10 seconds (1 = length, v = speed)
From statement II:
v = 10 m/sec
1 = 10 × v = 100 m
