Answer 1

The total amount is 116.25 rupees.

Step-by-step explanation:

Let 1 rupees coin = 6x, 50 paise coin = 3x and 25 paise coin = x

Given, total number of coins = 150

To find, the total amount = ?

According to question,

6x + 3x + x = 150

⇒  10x = 150

⇒ $x=\dfrac{150}{10} =15$

∴ 1 rupee coin = 6 × 15 = 90

50 paise coin = 3 × 15 = 45 and

25 paise coin = 15

The total amount = 90 × 1 rupee + 45 × 50 paise + 15 × 25 paise

= 90 × 1 rupees + 45 × $\dfrac{1}{2}$ rupees + 15 × $\dfrac{1}{4}$ rupees

= 90 rupees + 22.5 rupees + 3.75 rupees

= 116.25 rupees

Hence, the total amount is 116.25 rupees.
