Step-by-step explanation:

3). Saving percentages of A, B and C are 30%, 25% and 20% respectively.

Now, (A×30)/100: (B×25)/100: (C×20)/100 = 4: 5: 6

Or, 3A/10: B/4: C/5 = 4: 5: 6

Or, 6A: 5B: 4C = 4/6: 5/5: 6/4

A: B: C = 2/3:1:3/2

Multiplying each ration by 6,

A: B: C = 4:6:9

Now the sum of the ratios = 4 + 6 + 9 = 19

Earning of B = (6/19) × 95000 = Rs. 30000

Earning of C = (9/19) × 95000 = Rs. 45000

Required difference = (45000 – 30000)

= Rs. 15000
