Answer 2

Answer:

Step-by-step explanation:

let number of 25 p coins be 'x' and number of 50 p coins be 'y'.

According to the question,

0.25 x + 0.50 y = 23.75 ⇒ equation 1.

x + y = 70 ⇒ equation 2.

Equation 1 ÷ 5 = 0.5 x - 0.1 y = 4.75 ⇒ equation 3.

Equation 3 × 10 = 5x - y = 47.5 ⇒ equation 4.

Equation 4 + Equation 2 = 6x = 117.5 ⇒ x = 19.58 (rounded off to 20)

x=20 , x + y = 70 ⇒ y= 70 - 20 ⇒ y= 50

This should be the answer otherwise the question is wrong
