Question

7.To stitch a shirt ,2m 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be

stitched and how much cloth will remain?

Answer 1

Answer:

18 shirt can be stitched and 1m 30cm cloth will remain

Step-by-step explanation:

here,

2m 15cm =2m+15/100m   =2.15m

finding no. of shirts,

              cloth(m)                                                    no. of shirts

                  2.15                                                               1

                  40                                                                 x

now,

2.15/40 =1/x                              

or,2.15x=40

or,x=40/2.15

x=18.60

no. of shirts=18

finding remaining cloth,

2.15 × 18    =38.7m                                              

again,

40-38.7     =1.3m

remaining cloth=1.3m     =1+0.3m      =1m+0.3 ×100cm =1m 30cm

hence,

the no. of shirt that can be stitched is 18 and the remainig cloth is 1m 30cm.

hope you find it helpful.<3
