A. 5
B. 12
C. 10

Nazir can wash 1/15 part of the car in 1 minute

His son can wash 1/30 part of the can in 1 minute

Together they can wash (1/15 + 1/30 = 1/10) part of the car in 1 minute

So, together they can wash the whole car in 10 minutes.

2711 . Nine identical machine, each working at same constant rate, can stitch 27 jerseys in 4 minutes. How many minutes would it take 4 such machines to stitch 60 jerseys?-

A. 8
B. 12
C. 18
D. 20

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

Let's break down the problem step by step:

1.Nine identical machines can stitch 27 jerseys in four minutes.
2.This means that one machine can stitch (27 jerseys) / (9 machines) = 3 jerseys in four minutes.
3.To find out how many jerseys one machine can stitch in one minute, we divide by 4 (since there are 4 minutes in one minute): 3 jerseys / 4 = 0.75 jerseys per minute per machine.
Now, we want to determine how many minutes it would take for 4 such machines to stitch 60 jerseys:

1.First, calculate how many jerseys 4 machines can stitch in one minute: 4 machines * 0.75 jerseys per minute per machine = 3 jerseys per minute for 4 machines.
2.To find out how many minutes it takes to stitch 60 jerseys at this rate, divide 60 jerseys by the rate of 3 jerseys per minute: 60 jerseys / (3 jerseys per minute) = 20 minutes.
So, it would take 4 machines 20 minutes to stitch 60 jerseys.

Answer: Option D

Explanation:

Let the cost price be A.

Then, A + 30% of A = 65

or, A + 0.3A = 65

or, 1.3A = 65

or, A = 65 / 1.3 = 50 TK.

New retail price at 10% profit = 50 + 10% of 50 = 50 + 5 = 55 TK
