ϙᴜᴇsᴛɪᴏɴ:

Rahul has a total of Rs 590 as currency notes in the denomination of Rs 50 Rs 20 and Rs 10. The ratio of number of 50 Rs notes and 20 Rs notes is 3:5. If she has a total of 25 notes ,how many notes of each denomination she Has ?

ᴀɴsᴡᴇʀ:

since total notes=25,

LET ₹50 notes=3A,

20 notes=5A,

then

10 notes=25-3A-5A-25-8A,

now ACCORDING to the question, We get

50×3A+20×5A+10×(25-8A)=₹590,

150A+100A+250-80A-590,

170A-590-₹250,

170A=340,

then,

A=340/170,

A=2,therefore

Rupee 50 notes=3x2=6,

Rupee 20 notes=5x2=10,

10 notes=25-6-10 = 9

Hope It'll HELPS!
