A family's earnings for 21 days is ₹770. Find its earning for 6 weeks and 3 days
Asked by jeenipicardo | 01 Feb, 2019, 07:14: PM
answered-by-expert Expert Answer
Earning for 21 days = Rs 770
6 weeks and 3 days = (6x7) +3 = 45 days
Applying the concept of proportionate ratios
770/21 = x/45
21x = 770 x 45
21x = 34650
x = 34650 / 21 = 1650
 
Earning for 6 weeks and 3 days is Rs. 1650
