Question

If the number of wells is 155 now, what was it 5 years back?

Answer 1

Answer:

31

Explanation:

Because If you divide

155/5=31 wells

Answer 2

The number of wells was 31, 5 years back.

• According to unitary method,

   In 5 years we have 155 wells

∴ In 1 year we have 155/5 = 31 wells

• As we do not have any other data in the question, so it is assumed that in the 1st year only 31 wells were there.
• Hence, the answer will be 5 years back there were only 31 wells.
