Money from different countries
Mithun’s uncle in America had sent him 10 USA dollars as a gift. Mithun used 350 rupees for a school trip. How much money was left with him?
उत्तर
Money received by Mithun = 10 USA Dollar
1 USA Dollar = 39.70
Hence, money received by Mithun
= 10 × 39.70
= 10 × 39 + 10 × 0.70
= 390 + 7
= 397 rupees
Money spent on school trip = Rs 350
Money left with him
= Rs 397 – Rs 350
= Rs 47
