Question

A wallet contains ₹4080 in notes in denominations of ₹10, ₹20, ₹50, and ₹100 in the ratio of 1 : 3 : 5 : 7 respectively. How much money do the 20 and 50 rupee notes sum up together? ​

Answer 1

Answer:

₹ 1240

Step-by-step explanation:

Let the common ratio of the given denominations be x.

So,

Sum of the notes of ₹10 = 10 *1 x = 10x,

Sum of the notes of ₹ 20 = 20 * 3x = 60x,

Sum of the notes of ₹ 50 = 50 * 5x = 250x and

Sum of the notes of ₹ 100 = 100 * 7x = 700x

Now,

A/q ,

10x + 60x + 250x + 700x = 4080

=> 1020x = 4080

=> x = 4080 / 1020

=> x = 4

Thus ,

Sum of the notes of ₹10 = 10x

= 10 * 4

= ₹ 40 ,

Sum of the notes of ₹ 20 = 60x

= 60 * 4

= ₹ 240 ,

Sum of the notes of ₹ 50 = 250x

= 250 * 4

= ₹ 1000 and

Sum of the notes of ₹ 100 = 700x

= 700 * 4

= ₹2800

Hence,

The 20 and 50 rupee notes will sum up together as ₹ 240 + ₹ 1000 = ₹ 1240
