Answer 2

Answer:

(11). 54, 81, 108 ; (12). 4 five-rupee coins.

Step-by-step explanation:

12). t + f = 36

2t + 5f = 84

t = 36 - f

2(36 - f) + 5f = 84

72 - 2f + 5f = 84

3f = 12

f = 4

A purse has 4 five-rupe coins.

11). x + y + z = 243

$\frac{1}{2}$ x = $\frac{1}{3}$ y = $\frac{1}{4}$ z ⇔ 6x = 4y = 3z

z = $\frac{4}{3}$ y = 2x

y = 1.5x

x + 1.5x + 2x = 243

x = 243 ÷ 4.5 = 54

y = 1.5(54) = 81

z = 2(54) = 108
