Question

two metres of cloth measuring 80 meters are sold together for rs.144. one piece was bought for rs.2 per meter and other for rs.1.50 per meter. find the length of each

Answer 1

Answer:

Clothes were 32m and 48 m Long

Step-by-step explanation:

Let the length of clothes be x and y

so

x+y=80................(1)

2x+1.5y=144.....(2)

from (1)

x=80-y

put value of x into (2)

2(80-y)+1.5y=144

160-2y+1.5y=144

160-144=2y-1.5y

16=0.5y

y=32

put value of y into (1)

x+32=80

x=48
