Why we subtract 282 from (3.2*10) and why we divide the whole thing by 40?

Run rate for first 10 overs is 3.20.
So 10 * 3.20=30 runs in 10 overs.
40 * how much gives 250 = ??? so that over all become 280.
So,
check from options 40 * 6.25 = 250
250 + 30 = 280
Option A is correct answer.

10 overs was completed with a run rate of 3.2 for over ....which means they scored 3.2 runs in single overs there for 3.2 x 10 = 32.
Target was 282 so subtract 282 by 32 therefore 282-32 = 250.
250 should be scored in 40 overs.
So, divide 250 by 40.
250/40 = 6.25.

282 ie the target run.
10 over + 40 over = 50 over ie in 50 overs 282 should be made in order to win.
So run rate in 50 over needed is 282/50 = 5.64.
USING METHOD OF DEVATION.
3.2--5.64= --2.44*10 = --24.4......deviation for 10 overs (equ 1).
(Let X be avg for next 40 overs).
(X--5.64)*40 = 40X--225.6.......deviation for 40 overs.
(Equ 2)
Solving equ 1 and 2 we get,
40X--255.6--24.4 = 40X--250.
X = 250/40 = 6.25 run rate required in 40 overs.
10 over + 40 over = 50 over ie in 50 overs 282 should be made in order to win.
So run rate in 50 over needed is 282/50 = 5.64.

X = 250/40 = 6.25 run rate required in 40 overs.

Sum(h+w+c)three years ago:
(x-3)+(y-3)+(y-3)=27*3,
x+y+z=90....................eqn(1),
sum(w+c)five years ago:
(y-5)+(z-5)=20*2.
y+z=50.........................eqn(2).
simplify 1&2.
