52) 2 trees are there. One grows at 3/5 of the other. In 4 years total growth of the trees is 8

ft. what growth will smaller tree have in 2 years.Sol) THE BIG TREE GROWS 8FT IN 4 YEARS=>THE BIG TREE GROWS 4FT IN 2YEARS.WHEN WE DIVIDE 4FT/5=.8*3=>2.4ans: 1.5 mt 4 (x+(3/5)x)=88x/5=2x=5/4 after 2 years x=(3/5)*(5/4)*2 =1.5

53) There is a six digit code. Its first two digits, multiplied by 3 gives all ones. And the next two digits multiplied by 6 give all twos. Remaining two digits multiplied by 9 gives allthrees. Then what is the code?sol) Assume the digit xx xx xx (six digits)First Two digit xx * 3=111

xx=111/3=37( first two digits of 1 is not divisible by 3 so we can use 111)Second Two digit xx*6=222

xx=222/6=37( first two digits of 2 is not divisible by 6 so we can use 222)Thrid Two digit xx*9=333

xx=333/9=37( first two digits of 3 is not divisible by 9 so we can use 333)

54) There are 4 balls and 4 boxes of colours yellow, pink, red and green. Red ball is in a boxwhose colour is same as that of the ball in a yellow box. Red box has green ball. In whichbox you find the yellow ball?Ans is green...Sol) Yellow box can have either of pink/yellow balls.if we put a yellow ball in "yellow" box then it wud imply that "yellow" is also the colour of the box which has the red ball(becoz acordin 2 d question,d box of the red ball n the ball inthe yellow box have same colour)thus this possibility is ruled out...therefore the ball in yellow box must be pink,hence the colour of box containin red ball isalso pink....=>the box colour left out is "green",,,which is alloted to the only box left,,,the one which hasyellow ball..

55) A bag contains 20 yellow balls, 10 green balls, 5 white balls, 8 black balls, and 1 redball. How many minimum balls one should pick out so that to make sure the he gets at least 2 balls of same color.Ans:he should pick 6 ball totally.Sol) Suppose he picks 5 balls of all different colours then when he picks up the sixth one, it


25/62

must match any on of the previously drawn ball colour.thus he must pick 6 balls

56) What is the number of zeros at the end of the product of the numbers from 1 to 100

Sol) For every 5 in unit palce one zero is added Ch eta naSso between 1 to 100 there are 10 nos like 5,15,25,..,95 which has 5 in unit place.Similarly for every no divisible by 10 one zero is added in the answer so between 1 to 10011 zeros are addedfor 25,50,75 3 extra zeros are addedso total no of zeros are 10+11+3=24

57) 10 Digit number has its first digit equals to the numbers of 1's, second digit equals tothe numbers of 2's, 3rd digit equals to the numbers of 3's .4th equals number of 4's..till 9thdigit equals to the numbers of 9's and 10th digit equals to the number of 0's. what is the
