- 18
{x1+x2+x3+..................x17+18}/18=18
x1+x2+...............x17=18{18-1}
x1+x2+..............x17}/17=18
hence 18 is required answer.

- total innings=18
avg=18
so total run at 18th innings is 18*18=324

- ya guys here we are ..i will explain this in a basic way
First we take first sentence ...so normally he scored some runs up to 17 innings and in 18 innings he scored 18 runs which means
x + 18
--------- = 18
18
so the above equation goes like this...his total average 18(given) and totally 18 innings(given) and x is the total runs in 17 innings + 18 innings run which is 18.
solving that u get x=306 ( which is , In 17 innings total runs scored by the batsman)
so
306
--- = ?(tats the answer :) )
17
306/17 = 18
and tats it ...do not complicate it..In maths whatever you feel from the question just write and solve you will get the answer easily !!! :p - 12 years agoHelpfull: Yes(5) No(0)
