Read the following sentence carefully and identify if there is any grammatical error in it. If you find any error, choose the part (A, B, C, or D) containing the error as your answer. If there is no error, choose option E.
By the time the guests arrive, (A)/ the chef already prepared a (B)/ delicious feast, and the aroma (C)/ of the freshly cooked dishes fills the air. (D)/ No error (E)
The sentence describes an event happening in the future, indicated by the phrase "By the time the guests arrive." However, the verb in part (B), "prepared," is in the past tense. This creates a tense disagreement with the rest of the sentence. To correct the error, we need to change the verb in part (B) to the present perfect tense. The present perfect tense is used to describe actions that happened in the past but have a result or relevance to the present.
If √3n 729, then the value of n is equal to:
(72× 52+ 1555 )/(79+60) = 2000 ÷ ?
(64/25)?× (125/512)?-1= 5/8
108² + 99 X 98² =?
...(0.125)³÷ (0.25)² x (0.5)² = (0.5)?-3
44% of 560 + 68% of 2160 × 5/12 =? + 32% of 920.
464 + 181 +? = (154 × 25) - (15) 2
(30 × 0.80)⁴ ÷ (2160 ÷ 60)⁴ × (54 × 16)⁴ = (6 × 4)?+5
√4096 + 4/5 of 780 − ? = 296
