it should be 21.5% not 215%...correct it

Question:

DIRECTIONS: What approximate value will come in place of the question mark?


59% of 245 - 20.5% of 145 =?

Options:
A) 100
B) 118
C) 140
D) 150
E) 175
Solution:
Ans:(b)

? = 59% of 245 - 20.5% of 145

\(\approx\) 60% of 245 - 20% of 145

\(\approx\) \(\left ( \cfrac {60}{100}\times245 \right )-\left ( \cfrac {20}{100}\times 145 \right )\approx 147-29 \approx 118\)
