Question
Read the sentence to find out whether there is an error
in it. The error, if any, will be in one part of the sentence. The letter corresponding to that part will be your answer. If the given sentence is correct as it is, mark the answer as 'No Error'. Anwar revealed that his mother is actively involved in keeping him informed about ongoing developments and underscores the unwavering support from their close circles.Solution
As per the follow up of parallelism concept, the usage of non finite verb "underscores" is grammatically incorrect which should be replaced with "underscoring" to make the sentence grammatically correct.
Evaluate:
β729 + β49 - β16 + 1/β64
Simplify:

(1/5)(40% of 800 β 120) = ? Γ 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 β 20% of 5280) = ? Γ· 3
β157464 =?
