Walking 5/6 of his usual speed, a man is 10 minute too late. The usual time taken by him to cover that distance is:
OPtion
1) 1 hour
2) 50 minute
3) 30 minute 30 second
4) 12 minute
5) 20 minute
6) 25 minute 45 second
7) 8 minute 20 second
8) 45 minute
9) 38 minute
10)None of these
Solution
With a speed of 5/6 th of the usual speed, the time taken is 6/5 th of the usual time.
therefore
(6/5 of usual time) - (usual time) = 10 minute
1/5 of usual time = 10 minute.
So, usual time = 50 minute

Code is obtained as follow
ZEE CINEMA = ACE EEIMNZ (After taking the letters in increasing order)
Sum of position of letters according to English alphabet is
(1+3+5)(5+5+9+13+14+26) = (9)(72)
ZEE CINEMA = 972
Similarly
SAHARA ONE = AAAEHN ORS (after taking the letters in increasing order) sum of position of letters according to English alphabet is
(1+1+1+5+8+14)(15+18+19) = (30)(52)
then
SAHARA ONE = 3052

Ram invests a sum of 8 lacs in two different businesses partly. In first business, he receives a profit of 3.5 lacs and in second business, he obtains a loss of 16 %. In overall business he obtains a profit of 40 %. The ratio of investments in first and second business is
Let the investments in two businesses are respectively x & y
Then according to given conditions
x + 350000 + y * 0.84 = 1.4 (x + y) (i)
x + y = 800000 (ii)
On solving these two equations , we get x = 612500 and y = 187500
