Step-by-step explanation:
1) ans. is 95 * 92 = Rs. 8740
2) volume of a cylinder is =r square h
= 22/7 * 6*6 *343/22
=343/7* 36
=49*36 = 1764
3) x + y = 197, Multiply it by 2 you will get
2 x+2y =394 now subtract 2x+3y = 492
y =98, x=99
Ans is 99 * 98 = 9702
4) 5p + 4s = 97
Now, multiply the equation by 97
You will get,
485p + 388s = 97* 97 = 9409 = Ans.
Now 1 - 997/998 = 1/998 where as 1- 989/995 = 6/995
Now compare,
1/998 6/995 we get by cross multiplying
So, as the number we have to add to 997/998 is smaller, 997/998 is bigger
Ans. is 997/998
