Question

Pawan is a cashier in a bank. He has currency notes of denominations 1000 and 100 respectively. The ratio of the number of these notes is 4:10. If the total cash with Pawan is Rs.5,00,000, how many notes of Rs.1000 denomination does he have? (3 marks)

Answer 1

Given that the denomination notes of 1000 and 100 are in the ratio 4:10,

No. of 1000 denomination notes Pawan has = $4x$

No. of 100 denomination notes Pawan has = $10x$ (1 mark)

For 1000 notes, amount of money
$=Rs.4000x$

For 100 notes, amount of money
$=10x\times 100=Rs.1000x$ (1 mark)

Total sum
$=4000x+1000x=Rs.5,00,000$ (Given)

$5000x=5,00,000$

$x=100$

Number of 1000 denomination notes
$=4\times 100=400$ notes (1 mark)
