Question

A pen set having two pens costs rupees 250. If it is known one pen costs 3/2 times that of the other, find the cost of each pen separately.

Answer 1

Answer:

100,150

Step-by-step explanation:

let one pen cost =x

another pen cost=y

given y=3/2x:::::x=2/3y

x+y=250

3/2y+y=250

(3/2+1)y=250

5/2y=250

y=250*2/5

y=50*2

y=100

x=2/3y

x=2/3*100

x=150

Answer 2

Answer:

the cost of two pens is 250

first pen = 3x

second pen=2x

3x+2x=250

5x = 250

x= 50

so 1st pen = 50×3 = 150

2nd pen = 50×2 = 100
