Aruna has only Rs 1 and Rs 2 coins with her. If the total number of coins that she has is 50 and the amount of money with her is Rs 75, then the number of Rs 1 and Rs 2 coins are, respectively 25 and 25. Explanation: Let the number of Rs 1 coins = x And number of Rs 2 coins = y x + y = 50 ..........(i) Also, (x $\times$ 1) + (y $\times$ 2) = 75 $\Rightarrow$ x + 2y = 75 ........(ii) On subtracting (i) from (ii), we get y = 75 – 50 = 25 When y = 25, then from (i), x = 25
