A + B = 1/30

B = 5/1 * 16 = 80 days

A = 1/30 – 1/80

A = (8 – 3)/240 = 5/240

A = 1/48

A complete the 75% of the work in = 48 * ¾ = 36 days

Total time period is not given.

Hence, the question cannot be answered.

SI = (P * N * R)/100

SI = 17600 – 8000 = Rs.9600

9600 = (8000 * 15 * x)/100

x = 8 years

Speed of stream = ¼ * 20 = 5 kmph

Speed of the boat along with stream = 20 + 5 = 25 kmph

Speed of the boat against the current = 20 – 5 = 15 kmph

Required ratio = 15: 25

= 3: 5

Distance = Speed * Time

Speed of car = 840/14 = 60 kmph

Speed of the bike = 4/3 * 60 = 80 kmph

Speed of the bus = ½ * 80 = 40 kmph

Distance covered by in 8 hours = 40 * 8 = 320 km

The pattern is as follows:

32 * 2.5 = 80

80 * 3.5 = 280

280 * 4.5 = 1260

1260 * 5.5 = 6930

6930 *6.5 = 45045  262144/8 = 32768

32768/8 = 4096

4096/8 = 512

512/8 = 64

64/8 = 8
