Answer 2

Number of Rs 100 notes = 2x

Number of Rs 50 notes = 3x

Number of Rs 10 notes = 5x

100(2x) + 50(3x) + 10(5x) = 4,00,000

200x + 150x + 50x = 4,00,00

400x = 4,00,000

$\bold x = \frac{4,00,000}{400}$

x = 1000

Number of Rs 100 notes = 2x = 2×1000 = 2000

Number of Rs 50 notes = 3x = 3×1000 = 3000

Number of Rs 10 notes = 5x = 5×1000 = 5000
