5.Ramesh bought a total of 6 fruits (apples and oranges) from the market. He found that he required one orange less to extract the same quantity of juice as extracted from apples. If Ramesh had used the same number of apples and oranges to make the blend, then which of the following correctly represents the percentage of apple juice in the blend?

E.None of the above

6. Sara has just joined Facebook.She has 5 friends. Each of her five friends have twenty five friends. It is found that at least two of Sara’s friends are connected with each other.

9.Ram, Shyam and Hari went out for a 100 km journey. Ram and Hari started the journey in Ram’s car at the rate of 25 kmph, while Shyam walked at 5 kmph. After sometime. Hari got off and started walking at the rate of 5 kmph and Ram went back to pick up Shyam. All three reached the destination simultaneously. The number of hours required for the trip was:


10.The central park of the city is 40 metres long and 30 meters wide. The mayor wants to construct two roads of equal width in the park such that the roads intersect each other at right angles and the diagonals of the park are also the diagonals of the small rectangle formed at the  intersection  of  the  two  roads.   Further,  the  mayor  wants  that  the area of the two  roads to be equal to the remaining area of the park. What should be the width of the roads?

A.10 metres
B.12.5 metres
C.14 metres
D.15 metres
E.16 metres


1. Option e.

2. Let the time taken be x minutes by each of them. They read x/2, x/3 and x/4 pages respectively. So, x = 72 and so, option a is correct.

3. Option c.

4. Sum of the 6 integers is 90. Median is 18 and so, we can have the middle two values as 18. a, b, 18, 18, e, f and f has to be maximized. Only mode is less than 18 and so, a, b can be equal to 1 each with the middle values being 17 and 19. So, e+f will be 52 and e will be 20 at minimum. So, maximum value of f will be 32. Option d.

5. He used 3 apples and 3 oranges. But, juice from 3 apples equals juice from 2 oranges. So, juice from 3 oranges equals juice from 4.5 apples. So, 3/7.5 = 40%. Option e.

6. Best case (for Sara i.e.) will be when all her friends are friends with each other. So, total of 105 invitations have to go out. Worst case, if there are just 2 of her friends who are friends with each other, she will need to send 5+2*23+3*24=123 invitations. Option d.

7. Option b. Check this link to understand maxima-minima questions.

8. plogq = qlogp

logq = log9 + logp

plog9 + plogp = 9plogp

(9p)^p = (p)^9p

9p = p^9

Option d.

9. A typical question based on an easy concept. Shyam and Hari will have to walk the same distance for them to reach together. Let this distance be x. So, Hari covered x km in the same time as Ram covered (100 – x)+(100 – 2x) = 200 – 3x. So,

(200 – 3x)/x = 25/5

x = 25 km. So, total time taken was 25/5+75/25 = 8 hours. Option a.

10. Let the width of the roads be x. So, area of the roads will be 40x + 30x – x^2. As this is equal to 600, we get:

x^2 – 70x + 600 = 0

x = 10. Option a.
