Given : A wallet contains ₹4080 in notes in denominations of ₹10, ₹20, ₹50, and ₹100 in the ratio of 1 : 3 : 5 : 7 respectively
To Find : How much money do the 20 and 50 rupee notes sum up together
Solution:
₹10, ₹20, ₹50, and ₹100 in the ratio of 1 : 3 : 5 : 7
Let say ₹10, notes = P
then ₹20 notes = 3P
₹50 notes = 5P
₹100 notes = 7P
Total Values = 10 * P + 20 * 3P + 50 * 5P + 100 * 7P
= 10P + 60P + 250P + 700P
= 1020P
1020P = 4080
=> P = 4
Value of 20 & 50 notes
= 20*3P + 50*5P
= 60P + 250P
= 310P
= 310 * 4
= 1240 Rs
20 and 50 rupee notes sum up together = Rs 1240
