A merchant had Rs 78,592 with her. She placed an order for purchasing 40 radio sets at Rs 1200 each. How much money will remain with her after the purchase?
Cost of one radio set = Rs 1200
Cost of 40 radio sets = 1200 × 40 = Rs 48000
Money with Merchant = Rs 78,592
Money spent = Rs 48,000
Money left = 78592 − 48000
Therefore, Rs 30,592 will remain with her after the purchase.
