(4) Aruna has only Re1 and Re 2 coins in her piggy bank. If the total number of coins is
50 and the coins amount to Rs. 75. If 'X' be the number of Re1 coins and 'y be the
number of Re 2 coins, the equations so formed for the conditions are:
(a) x + 2y = 50; x + y = 75
(b) x + y = 50; x + 2y = 75
(c) x + y = 75 ; x + y = 50
(d) x - y = 50; x + 2y = 75​
