A sum of 1000Rs. is in the form of denominations of 10Rs. and 50Rs. If the total number of notes is 60, find the number of notes of each type.
​

Answer 1

Step-by-step explanation:

total sum= rs.1000

number of notes= 60

let number of rs.10 notes be x and number of rs.50 notes be y

:x+y=60

:x=60-y .eq.1

and 10x+50y=1000

.eq.2

substituting eq.1 in eq.2: 10(60-y) + 50y =1000

600-10y+50y=1000

40y= 1000600

40y=400

y=10

x=60-y

x=50

ans. number of:

10 rupee notes is 50 and 50 rupee notes is 10

Answer 2

Answer:

There are 10 RS 10 notes and 50 RS 50 notes

Step-by-step explanation:

let R10 be the number of RS 10 notes and R50 be the number of RS 50 notes

1) R10 + R50 = 60

2) (10 * R10) + (50 * R50) = RS 1000

solve equation 1 for R10 and substitute for R10 in equation 2

R10 = 60 - R50

(10 * (60 - R50) + (50 * R50) = RS 1000

600 - 10R50 + 50R50 = 1000

40R50 = 400

R50 = 10

R10 = 60 - 10 = 50
