Let the number of Rs.50 notes be A and the number of Rs.100 notes be B According to the given information, A + B = 25 ……………………………………………………………………….. (i) 50A + 100B = 2000 ………………………………………………………………(ii) When equation (i) is multiplied with (ii) we get, 50A + 50B = 1250 …………………………………………………………………..(iii) Subtracting the equation (iii) from the equation (ii) we get, 50B = 750 B = 15 Substituting in the equation (i) we get, A = 10 Hence, Meena has 10 notes of Rs.50 and 15 notes of Rs.100.
