(a) The worth of x coins of ₹ 5 each ________.

(b) The worth of x coins of ₹ 2 each ________.

(c) The equation formed is ________.

(d) There are ________5–rupee coins and ________ 2–rupee coins.

Answer :

Let the number of coins of ₹5 = x


Then, number of coins of ₹2 = x


(a) Number of coins of ₹5 = x


So, worth of ₹5 of x coins = ₹5 × x = ₹5x


(b) Similarly, the worth of 12 of x coins = ₹2x


(c) The equation formed is 5x + 2x = 70


(d) 5x + 2x = 70


7x = 70


x = 10


There are 10 ₹5 coins and 10 ₹2 coins.
