First 100 natural numbers in the decimal system are converted to base 6 and their product is found. Find the number of consecutive zeros at the end of the product as counted in the base 6 system. a 124
b 130
c 140
d 120
e 136
if a:b =3:4, b:c=5:3. a:d=2:5, then what is c:d=?
Two cities X and Y lie on a straight line. Two menP and Q left simultaneously for Y and X from X & Y respectively.P reaches Y and immediately turnsturns around and moves towards X.On reachin X, again he turns around and moves towards Y. this kind of move continuous indefinetly. Q also travel in a similar manner. the distance between X and Y is 1000 m and the ration of speeds of P and Q is 3:2. find the distance travelled by P when he meets Q for the 4rth time.😐
Mr. Bajaj car failed after he had covered 1/4 of the distance from his home to his office.he then board a bus,, which takes him to his office. he realises that he reaches his office that day it took him 9 times as long travelling by bus as travelling by car.how many times the speed of the bus is the speed of the car.😁
Two cars simultaneously left two cities P and Q for Q and P respectively. Once they arrive at their respective destinations,they turn around and moves towards their starting points.they met for the first tym 22km from city Q.they meet for the 2nd time 10 km from city P.Find the distance PQ.
50!^20*60!^30...how many zeros are there???

in a square grid of 11rows X 11columns , all numbers present in each row and colum are in A.P. if difference between any 2 consecutive numbers in each row and column is 2, and the number in the middle row and middle column of grid is 22, find the sum of all numbers in the grid.
A number has exactly 32 factors out of which 4 are not composite. product of these 4 factors is 30. How many such numbers are possible ??
Number of zeroes in (123!)base6 ?? approach please
ABC is an equilateral Triangle of side 10. P and Q are the mid points of side AB and AC. Join them via a line PQ. Now we have a triangle APQ and a trapezium , PQBC. A circle is inscribed in the triangle APQ. Let it have a radius r. Now inside the trapezium, is it possible to draw two circles of same radii such that the two circles touch each other and touch each of the 4 boundaries.
It is not exactly a question, but a doubt. 
If x + y = 4 where x and y are positive numbers, then the maximum possible value of 1/x +1/y is ?
