उत्तर
We do it as follows:
⇒ 5 notes of 100 rupee - 5 × 100 = Rs 500
⇒ 1 note of 50 rupee - 1 × 50 = Rs 50
⇒ 18 notes of 10 rupee - 18 × 10 = Rs 180
⇒ 9 notes of 20 rupee - 9 × 20 = Rs 180
⇒ 28 coins of 5 rupee - 28 × 5 = 140
Money I got = Rs 500 + Rs 50 + Rs 180 + Rs 180 + Rs 140 = Rs 1050
Money I earned = Rs 1050 − Rs 919 = Rs 131
