Answer 1

Step-by-step explanation:

Let no. = 2x , 3x , 5x

Total rupees =

100×2x + 50×3x + 10×5x = 400x = 4 lack

x = 4000

So notes = 8000 12000 20000

no. = y , x , 3x

total money = 1×y + 2×x + 5×3x = y + 17x = 300

total coins = y + 4x = 160

winners = x

non winners = 63-x

total money = 100x + 25(63-x) = 3000

Answer 2

Answer:

Let Rs 100 be 2x

Rs 50 be 3x

Rs 10 be 5x

total money is 400000

so, 2x + 3x+ 5x = 400000

10x= 400000

x= 400000/10

x= 40000

2x = 2 x 40000 = 80000

3x= 3x 4000 = 120000

5x = 5x 40000= 200000
