Thursday - 4
Friday 3 -

### Q1

A boatman rows down stream at 6kmph on Wednesday. Find the speed of upstream and Speed of current?
A. 7 kmph B. 2 kmph C. 3 kmph D. 5 kmph

B
Downstream Speed = 6kmph
Upstream Speed = 8kmph – 6kmph = 2kmph
Speed of Current = $\frac {(6 - 2)}{2}$ = 2kmph

### Q2

What time will be taken by a boat to cover a distance on Tuesday along the stream, if the up stream of boat is 3 kmph?
A. 4 hours B. 5 hours C. 2 hours D. 3 hours

C
Upstream of boat = 3 kmph
Down stream of boat = 15 kmph
Down Stream Distance = 15% of 200 = 30; Time = $\frac {30}{15}$ = 2 hr

### Q3

What is the sum of total distance travelled by the boat on Monday, Wednesday and Friday together?
A. 316 B. 328 C. 356 D. 296

B
Total distance travelled by the boat on Monday = 48 + 90 = 138
Similarly Total distance travelled by the boat on Wednesday and Friday = 102, 88
Total distance travelled by the boat on Monday, Wednesday and Friday = 138 + 102 + 88 = 328 km

### Q4

Find the difference between the up stream distance travelled by boat on Tuesday and Friday together and the down stream distance travelled by boat on the same days together?
A. 12 km B. 18 km C. 16 km D. 14 km

D
Difference = 96 – 82 = 14

### Q5

Total downstream distance travelled by boat on Monday, Tuesday and Wednesday together is what percentage of total upstream distance travelled by boat on the same days together?
A. 48.6% B. 46.7% C. 48.5% D. 47.5%

A
Total downstream distance travelled by boat on Monday, Tuesday and Wednesday = 108
Total up stream distance travelled by boat on Monday, Tuesday and Wednesday = 222
% = $\frac {108}{222} \times$ 100 = 48.6%
