Question

Mark (✓) against the correct answer
What should be added to 2.06 to get 3.1?

(a) 1.4
(b) 1.24
(c) 1.04
(d) none of these

Answer 1

Option (c) is correct.
Let the number added be x.
We have:
2.06 + x = 3.1
⇒ x = 3.1 − 2.06

Converting the given decimals into like decimals, we get:
2.06 and 3.10
Thus, required number = (3.10 − 2.06) = 1.04

Hence, 1.04 should be added to 2.06 to get 3.1.
