Here 45/40 is for a game of point 60. They asked how many point can B give to C in a game of 90.
So convert B ie. 45 to 90 which is multiply (45 * 2) = 90 multiply by the same with 40 ie 40 * 2 = 80 then we get;
90/80 so B give C 10 points in a game of 90.

Your doubt is 90/80.
Because 40/45*90.
= 8/9*90.
9 divided by 90, answer is 10.
Then, 8*10 = 80.
B give C in a game of 90.
= 90/80. Ratio 90:80.
90-80 = 10.
Answer: B give C 10 points in a game of 90.
Because 40/45*90.
= 8/9*90.
9 divided by 90, answer is 10.
Then, 8*10 = 80.
B give C in a game of 90.
= 90/80. Ratio 90:80.
90-80 = 10.
Answer: B give C 10 points in a game of 90.

How it will come 90/80? Because 90 is a total points, please clear my doubt?
Solved it as 45/60*60/40 which gives the result of 45/40 i.e., in the form of ratio it is 45:40 means for 45 points he give 40 points. But here they asked for 90 points.
