As per the question, instead of 1 mobile(M), one can purchase 2 pen drives(PD). ∴ Price of 1 M = price of 2 PD Given, price of 3 M + 6 PD = 9,000 ∴ Price of 3 M + 3 M = 9,000 (As 6 PD = 3 M) ∴ 6 M = 9,000 ∴ 1 M = Rs.1, 500 and Price of 1 PD = Rs. 750 ∴ Reqd. difference = Rs.1, 500 - Rs. 750 = Rs. 750
