Answer 1

Number of rolls of cloth that will be cut by Reena is 108. so option (a) is correct choice.

Reena cuts a roll of cloth into 10 equal pieces. she can make 36 cuts a minute.

We have to find the number of rolls of cloth that will be cut by Reena in 27 minutes.

we know, One cut makes two pieces.

∴ 9 cuts will make (9 + 1) = 10 pieces of cloth. ...(1)

∵ Reena can make 36 cuts a minute.

∴ number of cuts made by her in 27 minutes = 36 × 27

hence number of rolls of cloth = 36 × 27/9

[ from equation (1), a roll of cloth = 10 piece of cloth = 9 cuts ]

= 108

Therefore number of rolls of cloth that will be cut by Reena is 108. so option (a) is correct choice.
