Question

4 students started painting work
for greeting cards and completed
12 days. If 16 students will do
same work, how many days they
will require ?​

Answer 1

Answer:

4 students take 12 day

So, 1 student take = 4×12 = 48 days

Then 16 students will do same work = 48 ÷ 16

= 3 ans

Answer 2

Answer:-

Given:

• Number of students doing painting = 4

• Time taken by them to complete painting = 12 days

To Find:

• Time taken by 16 student to complete the painting.

Solution:

As, here the work will increase for only 1 person to complete a work so here we multiply;

Time taken by 1 student to complete it

= 12 × 4

= 48 days

As here the work will be distributed among different number of peoples.so, here we divide the work.

Time taken by 16 student to complete it

= 48 ÷ 16

= 3 days.

Hence, 16 students take 3 days to complete the painting.
