Answers:

1. 3)
12*18 : 9*12 : 8*9
= 6 : 3 : 2
3982/11 *(3-2) = Rs. 362

2. 4)
Let distance = x km
upstream speed = 8-6 = 2 kmph
downstream speed = 8+6 = 14 kmph
x(1/2 – 1/14) = 30
x = 70 km

3. 2)
diff between CI & SI for 3 yr = P(R/100)²(R+300)/100
37.20 = P(10/100)²(10+300)/100 = Rs. 1200

4. 2)
360*38 = 360*8 + 270*x
x = 40

5. 4)
(2628/40000)*100 = 6.57%

6. 4)
x[(1/3)(20/100) + (1/5)(30/100) + (7/15)(10/100)] = 156
x = 900

7. 3)
14x/6y = 14/15
x/y = 2/5

8. 3)
(3C3 + 5C3 + 4C3)/(12C3) = 3/44

9. 4)
(130/100)(120/100)*100 = 156
exceeds by = 156-100 = 56%

10. 2)
total amount invested = 2100*23/6 = 8050
annual = 8050*12 = Rs 96,600
