their is nothing tricky in the question.....!!
Just start solving according to the question
It's just a bit of calculation and all
take time as 50 hrs, 40 hrs ,20hrs for three tasks respcc.
now solve according to the question.....!!

Solution:
There is a repeat of of last digits after every 10th term. So all together there will be 12 sets.
=L((1+6+1+6+5+6+1+6+1+0)*12)
=L(33*12)
=6

@Exodia said:Mr. A is a computer programmer. He is assigned three jobs for which time is allotted in the ratio of 5:4:2 (jobs are needed to be done individually). But due to some technical snag, 10% of the time allotted for each job gets wasted. Thereafter, owing to the lack of interest, he invests only 40%, 30% and 20% of the hours of what was actually allotted to do the three jobs individually. Find how much percentage of the total time is the time invested by A.Options not available. Plz give answer alongwith explanation.
32.7%?

1 + 6 + 1 + 6 + 5 + 6 + 1 + 6 + 1 + 0 = 6
1 + 6 + 1 + 6 + 5 + 6 + 1 + 6 + 1 + 0 = 6

@iLoveTorres Can you explain a bit as all others have got 29.45 and I am getting that as well. Did you not consider the 10% of the time wasted?

1/(root3) ??
Let the triangle be of side x. Place a point P on the median such that it makes 90deg with side AB. let the distance of AP = BP = y. Now area of APB would be 1/2 *y*y = (x^2)/4. (Pythogoras). Now probability = area of APB/ area of ABC = ((x^2)/4)/ (sqrt3 x^2/4) = 1/sqrt 3 !!! Hope this is rite 😛 😃
