Question
Jar A contains ‘X’ ml mixture of milk and
water in the ratio of 4 :3. Jar B contains ‘X’ ml mixture of milk and water in the ratio of 5:1, When both jars are mixed in Jar C the what will be the ratio of milk and water in jar C?Solution
Jar A Milk Water 4 : 3 In Jar B Milk Water 5 : 1 Sum of first jar is 7 & that if second is 6. LCM of 7 & 6 is 42. So multiplying 1st by 6 & that of 2nd. In jar A, M:W = 24 : 18 In jar B, M:W = 35 : 7 So adding both values, in Jar C, M: W = 59 : 25
If 'x' = √6, then find the value of (x - 3)² + (x + 3)²
If P3 + 3P2 + 3P = 7, then the value of P2+ 2P is –

What will come in place of the question mark (?) in the following series?
23, 46, ?, 184, 368, 736
If 70% of ‘y’ is 25% more than 30% of 140, then value of ‘y’ is:
If  a2+2 = 2a
then find a4Â - a3Â + 2a2Â -2a+ 9 = ?
(123×123×123 + 130×130×130)/(123×123 - 123×130 + 130×130) = ?Â
The average of three numbers a, b and c is 2 more than c. The average of a and b is 48. If d is 10 less than c, then the average of c and d is:
If (a - b - c) = 6, and (ab - bc + ca) = 117, then find the value of (a 2 Â + b 2 Â + c 2 )
If (a2 + 1/a2) = 51, then find the value of (a3 - 1/a3).
