Correct Answer - Option 3 : 17
Given:
Total Money = Rs. 1500
Total number of ten and twenty rupee note = 42
The ratio of ten rupees and twenty rupees = 19 : 23
Calculation:
Amount By ten-rupee note = 19 × 10 = 190
Amount By twenty rupee note = 23 × 20 = 460
Amount by ten and twenty rupee note
⇒ 190 + 460
⇒ 650
Left amount = 1500 - 650 = 850
Fifty rupee note
⇒ 850/50
⇒ 17
∴ The number of fifty rupee note is 17.
