If a person works all the 30 days of a month, he gets Rs. 42 per day and for taking leave he is fined Rs. 2 per dya. If he got Rs. 952 in the month, then the number of days he did not work was.

** Option:**

**A.**6

**B.**8

**C.**9

**D.**7

**Answer: D . 7**

** Justification:**

Suppose, number of days he was absent = $x$

So, Salary to be deducted = Rs.2 x $x$ = Rs.$2x$

Salary for working $(30-x)$ days = Rs. $(30-x)$ 42

By hypothesis,

$(30 - x) 42 - 2x$ = 952

or 1260 - $42x - 2x$ = 952.

or $44x$ = 1260 - 952 = 308.

or $x = 308/44$ = 7 days.

Hence, person did not work for 7 days.
