Let the common ratio between the numbers of notes of different denominations be x. Therefore, numbers of Rs 100 notes, Rs 50 notes, and Rs 10 notes will be2x, 3x, and 5x respectively. Amount of Rs 100 notes = Rs (100 × 2x) = Rs 200x Amount of Rs 50 notes = Rs (50 × 3x)= Rs 150x Amount of Rs 10 notes = Rs (10 × 5x) = Rs 50x It is given that total amount is Rs 400000. ? 200x + 150x + 50x = 400000 ? 400x = 400000 On dividing both sides by 400, we obtain 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 |
