**Aruna has only ₹ 1 and ₹ 2 coins with her. If the total number of coins that she has is 50 and the amount of … 15 and 35 …**

###### Answers:

(d) Let number of ₹ 1 coins = x

and number of ₹ 2 coins = y

Now, by given conditions x+y=50 …(i)

Also, x×1+y×2=75

⇒ x + 2y = 75 …(ii)

On subtracting Eq. (i) from Eq. (ii), we get

(x + 2y) – (x + y) = 75 – 50

⇒ y = 25

When y = 25, then x = 25
