Question

I have Rs 5200 with me, as 20 Re., 50 Re. and 100 Re. notes in the ratio 3:2:1. how many 20 Re. notes are there with me?​

Answer 1

Answer:

hello,

ratio of no. of notes is 4:5:6

let the no. of Rs.10 note be 4x

Rs.20 note be 5x

and Rs.50 note be 5x

amount of Rs.10 note will be 4x×10=40x rupees

amount of Rs.20 note will be 5x×20=100x rupees

amount of Rs.50 note will be 6x×50=300x rupees

now,

total amount will be 40x+100x+300x

=440x rupees

but total amount is 4400 rupees

therefore,

440x=4400

x=10

therefore, 

no. of Rs.10 notes are 4x=40 notes

no. of Rs.20 notes are 5x=50 notes

no. of Rs.50 notes are 6x=60 notes

hence,Rs. 50 notes are 60 in no.
