Question

A wallet contains 4080 in notes in denomination of $10,$20,$50 and $100 in the ratio of 1:3:5:7 respectively how much money do the 20 and 50 rupee note sum up together

Answer 1

2040

Step-by-step explanation:

let take x as the value of notes

acc. to ques,

$10:$20:$50:$100 = 1:3:5:7

= x:3x:5x:7x

$10 = x

$20 = 3x

$50 = 5x

$100= 7x

total no of money =4080

now,

x+3x+5x+7x = 4080

16x= 4080

x = 4080/16 = 255

now,

$10 = 255

$20 = 3×255= 765

$50 = 5×255 = 1275

$100= 7×255= 1785

sum: $20+$50 =765+1275 = 2040

Hope this will help you :)

Answer 2

Since these are in the ratio so you gotta add the ratios and divide the amount by the sum of ratios to get the the sum of money each denomination contains
4080/16= 255
Sum of $10= 255
Sum of $20=765
Sum of $50= 1275
Sum of $100=1785
Sum of $20&50 =2040 in ₹ it would be 2014*75.12 = ₹153306
So it’s either 2040 but then the last statement of yours says Rs so it could be ₹153306
