2 trains started simultaneously at 11am from a to b , moving towards b to a respectively, and crossed each other at 3pm . if the train starting from a reached its destination 88 minutes before the other train, when did the train starting from b to a reach ?

Is there any other way we can solve this without using x?

Three years ago a friend offered me a used typewriter for Rs. 1,024. A year later he offered me the same for Rs. 640 and last year he wanted Rs. 400 and now he is willing to sell it to me for Rs. 250. But I have decided to buy it when he reduces the price next time. If he is constantly reducing its price, at what price will he offer the typewriter to me next? a. Rs. 150.45 b. Rs. 156.25 c. Rs. 211.25 d. Rs. 206.75 e. Rs. 202.25

Hi Vishal,The principle of depreciation is used hereAmount of after every depreciation = $$(1-\frac{x}{100})$$*A (Where A is the original amount)Here the depreciation factor = $$(1-\frac{x}{100})$$ = 1024/640 = 640/40 = 400/250= 1.6Therefore, the next price of the typewriter = 250/1.6 = 156.25Hope this helpsThanks

Hi Yogendra, Can you please elaborate your doubt.

I am able to solve several cat quotient and practice questions easily which makes me to ponder whether these are cat level.kindly clarify.

Some of the the questions in the cat quotient are from previous CAT papers and some are based on those and are of cat leve.

Answer the following questions based on the following Information: A basket contains 6 white balls, 4 red balls and 2 blue balls. In each turn a ball is picked from the basket and is kept back in the basket after noting its colour. After four turns, what is the probability that each color is picked atleast once?

Hi,Number of ways in which four balls can be picked such that each color is picked at least once = 6*4*2*6 + 6*4*2*4 + 6*4*2*2 = 288+192+96 = 576Number of ways in which fours balls can be picked randomly with replacement = 12*12*12*12 Therefore, required probability = 576/144*144 = 1/36Hope this helpsThanks

how do i solve para jumble

Hi Sachin, There are few concepts to keep in mind while attempting Para Jumbles. 1. Try to find Main Point of the paragraph. Every paragraph has an idea or a soul which should be identified. The sentences when constructed in the correct order reflect that idea. Try to find that idea and see what role a particular sentence will play in depicting the entire picture. Then arrange them accordingly to make paragraph coherent. 2. Try to see verbal connectives and logical connectives. These give hints regarding the sentences which follow and help in constucting a paragraph logically. 3. Try to see analogies as they should proceed with real life examples. Hope this will help you. All the best.

In a aeroplane, the fuel burnt is directly proportional to the square root of its speed. If the aeroplane travels 800 km at a speed of 441 km/hr, the amount of fuel burnt is equal to 1250 litres. Find the distance travelled by the aeroplane, if 2000 litres of fuel was burnt while travelling at 784 km/hr.Explain its,solution

Fuel burnt = k*root(speed) + fixed variable here distance1250 = k* 21 + 800 --> k = 450/21sim,2000 = 450/21*28 + xx=1400

How many point in the region enclosed by y>=|x-5| and y<=5 have integral coordinates ? Ans is 36 .. If i apply picks theorem i am getting 32 . kindly help

By drawing the given lines in graph, it formes a triangle with vertices: (0,5), (10,5) and (5,0).So the number of integral co-ordinates = 1(y=0)+3(y=1)+5(y=2)+7(y=3)+9(y=4)+11(y=5)=36.
