Question

to stich a shirt , 2ml 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be stitched and how many cloth will remain?

Answer 1

First we have to convert higher units into lower units i.e. from meters to cm. 

So, Total Cloth required to shirt one shirt = 2 m 15 cm
                                                                 = 2 x 100 + 15 cm
                                                                 = 215 cm 

And, Total length of cloth = 40 m
                                        = 40 x 100
                                        = 4000 cm

Now, The number of shirt which can be stitched out of 4000 cm length of cloth = 4000 / 215
= 18 shirts + 130 cm remaining cloth

As, Quotient = 18 & Remainder = 130

∴ 18 shirts can be made with a remaining of 130 cm of cloth.

Hope This Helps :)
