Out of all the 2-digit integers between 1 and 100, a 2-digit number has to be
selected at random. What is the probability that the selected number is not
divisible by 7?

**A. ** 13/90

**B. ** 12/90

**C. ** 78/90

**D. ** 77/90

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

**Explaination / Solution: **

The number of 2 digit multiples of 7 = 13

The number of 2 digit multiples of 7 = 13

Probability of choosing a number

Not divisible by 7 = (90-13)/90 = 77/90

The given question is followed by two statements: select the most appropriate option that solves
the question

**A. ** Statement I alone is sufficient

**B. ** Statement II alone is sufficient

**C. ** Either statement I or II alone is sufficient

**D. ** Both the statements I and II together are sufficient

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

**Explaination / Solution: **

Statement I can be used to solve the question if capacity of both tanks is already known Statement-II can be used if it is known what quantity of each tank is full/empty. Therefore, by using both statements Let capacity of tank B is x

Capacity of a solution tank A is 70% of the capacity of tank B. How many gallons of solution are
in tank A and tank B?

Statements:

I. Tank A is 80% full and tank B is 40% full

II. Tank A if full contains 14,000 gallons of solution

Statement I can be used to solve the question if capacity of both tanks is already known Statement-II can be used if it is known what quantity of each tank is full/empty. Therefore, by using both statements Let capacity of tank B is x

(70/100)x = 14000

x = 20000 gallons

Solution in tank A = (80/100)×14000 = 11200 gallons

Solution in tank B = (40/100) × 20000 = 8000 gallons

Total solution = 11200 + 8000 = 19200 gallons

P, Q, R and S are working on a project. Q can finish the task in
25 days, working alone for 12 hours a day. R can finish the task in 50
days, working alone for 12 hours per day. Q worked 12 hours a day
but took sick leave in the beginning for two days. R worked 18 hours
a day on all days. What is the ratio of work done by Q and R after 7
days from the start of the project?

**A. ** 10:11

**B. ** 11:10

**C. ** 20:21

**D. ** 21:20

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

**Explaination / Solution: **

After 7 days from start of project:

Q took sick leave on first 2 days

∴ Man hours by Q = 5×12

∴ Work done by Q = 5 × 12 × 1/(25×12) = 1/5

Man hours by R = 7×18

∴ Work done by R = 1/(50×12) × 7 × 18 = 21/100

∴ Ratio of work done by Q to work done by R = 1/5:21/100 = 100/(5×21) = 20/21
