Let the number of:
Rs 100-notes = 2x
Rs 50-notes = 3x
Rs 10-notes = 5x
∴ Value of Rs 100-notes = 2x cross times Rs 100 = Rs 200x
Value of Rs 50-notes = 3x cross times Rs 50 = Rs 150x
Value of Rs 10 we have 10-notes = 5x cross times Rs 10 = Rs 50x
According to the condition, we have
Rs 200x + Rs 150 x + Rs 50x = Rs 4,00,000
or 200x + 150x +50x = 400000
or 400x = 400000
Dividing both sides by 400, we have
x = 400000 divided by 400 = 1000
∴ 2x = 2 cross times 1000 = 2000
3x = 3 cross times 1000 = 3000
5x = 5 cross times 1000 = 5000
Thus, the number of
Rs 100-notes =2000
Rs 50-notes = 3000
Rs 10-notes = 5000
