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

**Explanation:**

Lets assume it has taken x years to the female employee to reach the rule of 70.

**Explanation:**

In the case of semi annual compounding, Interest rate becomes half and Number of periods becomes 2 per year.

So A = P(1+R100)^n

A=10,000(1+4100)^2 = 10000 * 2625 = 10816

Interest = (A-P) = (10816 - 10000) = 816

198. College T has 1000 students. Of the 200 students majoring in one or more of the sciences,130 are majoring in Chemistry and 150 are majoring in Biology. If at least 30 of the students are not majoring in either Chemistry or Biology, then the number of students majoring in both Chemistry and Biology could be any number from

**Answer:**** Option C **

**Explanation:**

If we assume exactly 30 students are not majoring in any subject then the students who take atleast one subject = 200 - 30 = 170

We know that n(A?B) = n(A) + n(B) - n(A?B)

=> 170 = 130 + 150 - n(A?B)

Solving we get n(A?B) = 110.

i.e., Students who can take both subjects are 110

But If more than 30 students are not taking any subject, what can be the maximum number of students who can take both the subjects?

As there are 130 students are majoring in chemistry, assume these students are taking biology also. So maximum students who can take both the subjects is 130

So the number of students who can take both subjects can be any number from 110 to 130

199. After loading a dock, each worker on the night crew loaded 3/4 as many boxes as each worker on the day of the crew. If the night crew has 4/5 as many workers as the day crew, what fraction of all the boxes loaded by two crews did the day crew load?

**Answer:**** Option D **

**Explanation:**

If there are x workers in day and each loaded y boxes

then boxes loaded in day =xy

boxes loaded in night = 3/4 *y*4/5 *x = 3/5 *xy

total boxes loaded = xy+3/5 *xy = 8/5 xy

fraction of all the boxes loaded by two crews did the day crew load = xy/(8/5 *xy) =5/8

200. The present ratio of students to teachers at a certain school is 30 to 1. If the student enrollment were to increase by 50 students and the number of teachers were to increase by 5, the ratio of the teachers would then be 25 to 1 What is the present number of teachers?

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

**Explanation:**

Given the ratio of students and teachers = 30:1

=> students and teachers are in school 30x, x respectively.

After new recruitments of students and teachers the strength becomes (30x + 50), (x + 5) respectively.

So, the new ratio = 25 : 1

(30x + 50)/(x + 5) = 25/1

=> 30x + 50 = 25x + 125

=> 5x = 75 => x = 15
