A shopkeeper sells pencils, erasers and sharpeners in three types of packs – Type 1, Type 2 and Type 3. Each pack of Type 1 contains three pencils, four erasers and six sharpeners. Each pack of Type 2 contains five pencils, two erasers and three sharpeners. Each pack of Type 3 contains four pencils, three erasers and five sharpeners. If a person wants to buy exactly 55 pencils, 50 erasers and 75 sharpeners, how many packs of Type 3 must he buy?

a dishonest shopkeeper increased 80% fixed price of his article and after that he gives 25% discount. if shopkeeper is taken 20% more quantity per kg by wholesaler and given 10% reduce per kg to customer. then what is net profit percent?
- Each of Alok, Bhadri and Challam were given a different six-digit number, in each of which the second digit from the left (i.e., the ten thousands digit) was replaced with the symbol x. Each of them was then told that the six-digit number given to him was divisible by a certain divisor d, and was asked to determine the value of x. While each of Alok and Bhadri came up with exactly three possible values for x, Challam came up with exactly four possible values. Which of the following could be a possible value of d?
- 16
- 30
- 27

Everyday, Anil's driver takes the car from Anil's home at certain time, reaches his office exactly at 5 p.m., picks up Anil and drives him home, travelling at a constant speed throughout. One day, Anil left his office at 3 p.m. and started walking on the usual route towards his home. His driver picked him on the way and drove him home. Anil noted that he reached home 40 minutes earlier than his usual time.
How long did Anil walk?

P and Q are two points 100 km apart. A starts running from P towards Q at 10 km/hr. B starts running from Q at exactly the same time and in the same direction as that of A at 20 km/hr. After an hour, B turns back and changes his speed to 10 km/hr. After another hour, B again turns back and changes his speed to 20 km/hr. He keeps on changing his speed and direction in this manner till the time he meets A. After how much time will A and B meet for the first time?
Ans is 20 hrs
There is a circular race-track of diameter 1 km. Two cars A and B are standing on the track diametrically opposite to each other. They are both facing in the clockwise direction. At t=0, both cars start moving at a constant acceleration of 0.1 m/s/s (initial velocity zero). Since both of them are moving at same speed and acceleration and clockwise direction, they will always remain diametrically opposite to each other throughout their motion. At the center of the race-track there is a bug. At t=0, the bug starts to fly towards car A. When it reaches car A, it turn around and starts moving towards car B. When it reaches B, it again turns back and starts moving towards car A. It keeps repeating the entire cycle. The speed of the bug is 1 m/s throughout. After 1 hour, all 3 bodies stop moving. What is the total distance traveled by the bug ? Okay, so here is a hint :- Now, let’s try to visualize the path of the bug. The question states that it will always be moving towards one of the cars. But the cars themselves are moving. So, bug’s path would not be a straight line. It would be a complicated spiral like path. Plus, the cars are not moving at constant velocity. They are accelerating, this will further complicate the spiral path. So, the approach is clear. We need to find mathematical equation corresponding to bug’s path for one cycle. Then we can simply calculate the distance from this equation and a little integral calculus. Then multiply the answer with the number of cycles. Plzzz solutn and approach... I solved it half bt little bit confuse....

A and B start swimming simultaneously from two points P and Q respectively, on a river towards each other. A crosses a floating cork at a point S and B crosses the floating cork at a point T which is at a distance of 8 km from point S. A and B cross each other at a distance of 2 km from T. It is given that the direction of flow of the river is from P to Q and in still water, the ratio of speeds of A and B is 3 : 1. P, S, T and Q ( in that order) are on the same straight line and assume that A, B and the floating cork move along that line.
Find the ratio of the upstream speed of A to the downstream speed of B.
