Question
His maid servant behavior (A)/ is undoubtedly indecent
(B)/ but I don’t understand (C)/how he tolerates it (D)/ No Error (E). In these questions some of the sentences have errors and some have none. Find out which part of a sentence has an error and indicate it corresponding to the appropriate letters. If there is no error, indicate corresponding to the last option.Solution
Replace ‘‘servant’’ with ‘‘servant’s’’. The presence of the noun ‘behaviour’ after ‘servant’ justifies the use of ‘s and meaning of the sentence. Hence option ‘A’ has the error.
Evaluate:
√729 + √49 - √16 + 1/√64
Simplify:

(1/5)(40% of 800 – 120) = ? × 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 – 20% of 5280) = ? ÷ 3
∛157464 =?
