185. There are equal number of boys and girls in a class. If 12 girls entered out, twice the boys as girls remain. What was the total number of students in a class?

**Answer:**** Option A **

**Explanation:**

Lets assume total number of boys = y

Total number of girls = x

Given:

Equal number of girls and boys

=> x/y=1/1 => x = y

If 12 girls are entered out,

=> x-12 = x/2

=> x=2x-24 => x=24

So, girls x=24 and boys y=x=24

So, total number of students = x+y

=> 24+24 => 48

186. A tank contains 10,000 gallons of a solution that is 5 percent sodium chloride by volume. If 2500 gallons of water evaporate from the tank, the remaining solution will be approximately what percentage of sodium chloride?

**Answer:**** Option B **

**Explanation:**

Sodium chloride in the original solution = 5% of 10000 = 500

Water in the original solution = 10000 - 500 = 9500

If 2,500 Liters of the water is evaporated then the remaining water = (9500 - 2500) = 7000

Sodium chloride concentration = 500/(500+7000) * 100 = 6.67 %
