Q-(8) Sol-(1)
A:B
12×3750=x×15000
x=3 months
B joined the business after 9 months.
Q-(9) Sol-(3)
Let the upstream speed be x kmph and downstream speed be y kmph. Then Distance covered upstream in 8 hours 48 minutes = distance covered downstream in 4 hours
Ratio between the speed of the boat and speed of the water current
½ (x+y): ½ (y-x) ? ½ (x+11x / 5) = ½ (-x + 11x/5)
8/5: 3/5 = 8:3
Q-(10) Sol-(1)
