__Solutions:__

**Ans.1(1)** Time taken by boat A in downstream

= 625/48=13.02 hr.

Time taken by boat E in downstream

= 550/24=22.91

Total time taken by (A+E)=35.93

Time taken by boat D in upstream=450/10 = 45

reqiured %= 45-35.93/45 × 100 = 20.15% 35%

**Ans.2(4)** Speed of boat G =30×120/100 =36 km/hr.

Speed of stream for boat G = 10×150/100 =15 km/hr.

Time taken by boat G in upstream

=1750/36-15= 1750/21 = 83.33 hour

Time taken by boat C in upstream

= 1750/16 hour

=109.375 hour

required difference= 109.37-83.33 = 26.04 hour

**Ans.3(2)** New distance= 2500×60/100 = 1500 km

Time taken by boat E to cover new distance (upstream)

= 1500×22%/8

= 330/8hours

time taken by boat A to cover old distance in downstream

required ratio = 330/8×48/625 = 330×6/625 = 396:125

**Ans.4(4)** time taken by boat A in upstream =625/18 =34.72 hour

time taken by boat B in upstream = 375/15 = 25 hour

time taken by boat C in upstream =500/16 = 31.25 hour

time taken by boat D in upstream = 450/10 = 45

time taken by boat E in upstream = 550/8 = 68.75 hour average time

time taken by boat C = 1256 /44 = 28.5429 hour

required difference = 41 hour-29 hour =12 hour

**Ans.5(5)** Time taken by abhinav(using boat B)

= 350/ ( 25 + 10 ) 350/35 = 10 hour

Time taken by Abhay (using D+E)

= 240/36 + 110/24

= 11.25 hour (approx)

required time = 11.25 hour- 10 hour =1.25 hour

**Ans.6(3)** The pattern is:

6 × 1 + 7 × 1 = 13

13 × 2 + 6 × 2 = 38

38 × 3 + 5 × 3 = 129

129 × 4 + 4 × 4 = 532

532 × 5 + 3 × 5 = 2675

**Ans.7(5)**

**Ans.8(1)**

**Ans.9(4)** The pattern of given series is:-

14 = 25 × 0.5 + 1.5

16 = 14 × 1 + 2

26.5 = 16 × 1.5 + 2.5

? = 26.5 × 2 + 3

? = 56

143.5 = 56 × 2.5 + 3.5

434.5 = 143.5 × 3 + 4

Thus, missing number is 56.

**Ans.10(2)** 0=(49÷7)-7

7=(0×7)+7

-6=(7÷7)-7

-35=(-6×7)+7

-12=(-35÷7)-7

77=(-12×7)+7
