42 (Question: 113637.0 )

plzzz describe this

Question:

DIRECTIONS: What should come in place of the question mark (?) in the following question?


64% of 842 - 7% of 426 = ?% of 3344

Options:
A) 34
B) 38
C) 42
D) 46
E) None of these
Solution:
Ans: (e) None of these

64% 842 - 7% of 426 = ? % of 3344 

\(\cfrac{64}{100} × 842 - \cfrac{7}{100} × 426 = \cfrac{?}{100} × 3344 \)

538.88 - 29.820 = ? × 33.44

509.60 = ? × 3344 

? =  \(\cfrac{509.60}{33.44}\) = 15.5

Okay See:

64% of 842 - 7% of 426 = ?% of 3344

64/100 * 842 - 7/100 * 426 = ?/100 * 3344

64*8.42 - 7*4.26 = /*33.44

Now, use approximations,

(64*8 - 7*4)/33 =?
? = (512 - 28)/33 = 484/33 = 14.66 = 15 approx

Now value around 15 is present in the option, so none of these is correct answer.
