Answer 1

100×2x + 50×3x + 10×5x = 400000 So, 400x = 400000 X = 1000 100 rs note = 2000 50 rs note = 3000 10 rs note = 5000

Answer 2

Let the number of three notes be 2x , 3X and 5x respectively

Total amount of Rs 100 = 100x2= 200x

Total amount of rs 50 =50x3 = 150X

Total amount of rs 10 = 10x5= 50x

A/Q

200X + 50X + 150X = 400000

400x = 400000

X= 400000/400

X= 1000

Number of 100 Rs notes =2x1000=2000

Number of rs 50 notes = 3x1000=3000

Number of rs 10 notes = 5 x 1000= 5000 Ans
