In 18 years A will be 5/4 times as old as B

(2x+18) = 5/4 * (x+18)

4(2x +18) = 5(x+18)

8x + 72 = 5x + 90

3x = 18

x = 6 which is the present age of B

sir I have another question from proportions.

The question is. A dealer mixes tea costing rs.6.92 per kg with tea coasting rs.7.77 per kg and sells the mixture at 8.80 per kg and earns a profit for 17 1/2% on his sale price. In what proportion does he mix them?

please send me the solution as soon as possible for my gmail.

Selling Price of 1 kg mixture = 8.8

Profit on his sale price = 8.8 * 17.5/100 = 1.54

Cost Price of 1 Kg mixture = 7.26

By rule of alligation

Cost Price of 1 Kg tea (type1) Cost Price of 1 Kg tea (type2)

6.92 7.77

\ /

Cost Price of

1 Kg mixture

7.26

/ \

/ \

(7.77-7.26) (7.26- 6.92)

Required ratio = (7.77-7.26) : (7.26- 6.92)

= 0.51 : 0.34

= 51 : 34

= 3 : 2
