B) 6 A 7 S 2 M 3 W 0 A 7

C) 6 S 7 M 2 S 3 W 0 M 7

D) 6 M 7 S 2 A 3 X 0 D

Answer: A

Explanation:By BODMAS rule

6 – 7 + 3 × 2 > 0/7

5. The average number of visitors of a library in the first 4 days of a week was 58. The average for the 2nd, 3rd, 4th and 5th days was 60.If the number of visitors on the 1st and 5th days were in the ratio 7:8 then what is the number of visitors on the 5th day of the library?

Answer:64

Explanation

If number of visitors on 1st, 2nd, 3rd, 4th & 5th day are a, b, c, d & e respectively, then

a + b + c + d = 58 × 4 = 232 ----(i) &

b + c + d + e = 60 × 4 = 240 ----(ii)

Subtracting (i) from (ii), e – a = 8 ---(iii)

Given

a/e=7/8 ---(iv)

So from (iii) & (iv) a=56, e=64

6. An exhibition was conducted for 4 weeks. The number of tickets sold in 2nd work week was increased by 20% and increased by 16% in the 3rd work week but decreased by 20% in the 4th work week. Find the number of tickets sold in the beginning, if 1392 tickets were sold in the last week

Answer: 1250

Explanation:

let initially A ticket has been sold.

So now in 2nd week 20% increases so

A × $\dfrac{{120}}{{100}}$

In 3rd week 16% increases so

A × $\dfrac{{120}}{{100}}$ × $\dfrac{{116}}{{100}}$

In 4th week 20% decrease so

A × $\dfrac{{120}}{{100}}$ × $\dfrac{{116}}{{100}}$ × $\dfrac{{120}}{{100}}$ = 1392

A = 1250

8. A constructor estimates that 3 people can paint Mr khans house in 4 days. If he uses 4 people instead of 3,how long will they take to complete the job?

a.4

b.2

a = 3

so answer is 3 days

9. The true discount on Rs. 2562 due 4 months hence is Rs. 122. The rate percent is:

A. 12%

B. 40/3%

C. 15%

D. 14%

Answer: C

Explanation:

Ans. C. 15%

The true discount on Rs. 2562 due 4 months hence is Rs. 122.

Therefore Present Worth is = 2562 – 122 = 2440.

It means that Rs. 122 is interest on Rs. 2440 for 4 months.

Therefore rate percent is = (122 × 100 × 12)/(2440 × 4) = 15%

10. Q is as much younger than R as he is older than T. If the sum of the ages of R and T is 50 years, what is definitely the difference between R and Q's age?

B. 2 years

C. 25 years

D. Data inadequate

E. None of these

Answer: C

Explanation:

Given

R – Q = Q – T and R + T = 50 which gives Q = 25

As the difference between R & Q and Q & T is same

So Answer is 25 years
