Question

Pawan is a cashier in a bank. He has currency notes of denominations 2000, 500 and 100 respectively. The ratio of the number of these notes is 1:3:5. If the total cash with Pawan is Rs.5,00,000, how many notes of Rs.2000 denomination does he have?

Answer 1

Given that the denomination notes of 2000, 500,100 are in the ratio 1:3:5,

No. of 2000 denomination notes Pawan has = $x$

No. of 500 denomination notes Pawan has = $3x$

No. of 100 denomination notes Pawan has = $5x$

For 2000 notes, amount of money = Rs. $2000x$

For 500 notes, amount of money = $3x\times 500$ = Rs. $1500x$

For 100 notes, amount of money = $5x\times 100$ = Rs. $500x$

Total sum = $2000x+1500x+500x=Rs.5,00,000$ (Given)

$4000x=5,00,000$

$x=125$

Number of 2000 denomination notes = 125 notes
