Share of profit = Amount invested × time

A = (14000 × 4) + (16000 × 20) = 376000

B = (12000 × 2) + (10000 × 18) = 204000

C = (2000 × 18) = 360000

Ratio of Share = 376 : 204 : 360

C's share = 94000/940 * 360 = 36000

7. 2

15/b = tan 60

15/b = v3

b = 15/v3

P/b = tan 30

P = 5

So, height of pole = 15 - 5 =10 m

8. 3

K * H = 240

K = 240/H

Also, 2k = H + 4

2 (240/H) = H + 4

H = 20

K = 240/20 = 12

Let the distance travelled at 40 kmh-1 = x km

? distance travelled at 30 kmh-1 = 300 - x

300/8 = 300/(x/40) + (300-x)/30

x = 240
