Anand earns ₹ 80 in 7 hours and promote ₹ 90 in 12 hours . The ratio of their earnings is

Answer 1

Find the amount Anand earn in an hour:

7 hours = Rs 80

1 hour = 80 ÷ 7 = Rs 80/7

Find the amount Promote earns in an hour:

12 hours = Rs 90

1 hour = 90 ÷ 12 = Rs 15/2

Find the ratio:

Anand : Promote = 80/7  : 15/2

Multiply by 2:

Anand : Promote = 160/7  : 15

Multiply by 7:

Anand : Promote = 160  : 105

Divide by 5:

Anand : Promote = 32 : 21

Answer: The ratio is 32 : 21
