Question 631353
A sum of Rs 2000 is in the denomination of Rs.50 and Rs.10 notes. if the total number of notes be 80. Find the number of notes of each type.
ans:-
let no of rs 50 notes=x
then rs 10 notes = 80-x
the value = 50x+10(80-x)=2000
or 50x-10x+800=2000
or 40x=2000-800=1200
or x=1200/40=30
so no of rs 50 notes=30
& no of rs 10 notes = 80-x =80-30=50 ans
