**DAY 3 QUESTIONS **

**Q.1) There are four persons A, B, C and D are sitting in a row. All are facing north. All of them has different ages 20yrs, 25yrs, 30yrs and 35yrs, but not necessarily in the same order. The number of persons sits between A and B is same as between C and D. A is not an immediate neighbour of B and D. The age of A is 30 yrs. The sum of the age of B and C is numerically same as the number of days taken by Arul to complete a piece of work. Arul and Bala together can complete the same work in 20 days. Bala can complete the same work in x days. 70% of its usual speed, a train of length 10x m crosses a platform of length 190m in 7 seconds. At its normal speed, the train crosses a pole in 3 seconds. The age of one who sits third to the right of A is z years.

b) 190

c) 185

d) 181

e) 180

**DAY 4 QUESTIONS **

**Q.1) Aryan can do a piece of work in 16 days. Due to some problem, his efficiency reduces to 40%. Ankur’s efficiency also reduces to two-third of his original efficiency. Now they can finish the work together in 20 days. The number of days can Ankur and Aryan together finish the work at 100% efficiency is numerically equal to the length (in m) of the rectangle. Distance travelled by train whose speed is 72km/hr in seconds is equal to perimeter of the rectangle. Find the area of the rectangle?**

a) 75m²

b) 100m²

c) 50m²

d) 88m²

e) 112m²

## DAY 5 Questions

**Q.1) 700, 720, 820, 1020, 1340, ___ , the number missing in the given number series is numerically equal to the amount invested by sarkar in bank A. x²-7x-450=0 the positive value of x is numerically equal to the rate of interest per annum(@ S.I) given by Bank A. **

**35% of 4580 – 48 ×72 + 93× 97 = y + 4168 the value of y is numerically equal to the amount invested by viswasam in bank B which gives 30% rate of interest per annum at simple interest. The difference between the interest received by Sarkar and the interest received by viswasam is Rs.1800. **

## DAY 6 Questions

Q.1) A tank is fitted with 12 pipes. Some of them are inlet and some of them are outlet. Each inlet pipe can fill the tank in 10 hours and each outlet pipe can empty the tank in 8 hours. If all the pipes are opened together the tank will be filled in hours. The number of outlet pipes is numerically equal to the number of years invested by a person in a bank. The amount which he invested is Rs.29120 and the rate of interest is 20% @ C.I. The interest amount he received from the bank is numerically equal to the area of a square. The perimeter of the square is numerically equal to the value of x.

remove the name blue whale, its anti social… the maniac is long gone and its like you are reminding it again, whats your intention?

Hi Ravi Kiran,

Have you checked the Actual Details of Blue Whale ?

The Questions are in the extreme Level and to insist on that , we use the name “Blue Whale”.

No other intention to remind the game again. Also we are equally responsible for what we are saying and we have already mentioned that clearly in the post.

Hope this clarifies.
