Question
The smallest fraction, which should be added to the sum
of2(1/2), 3(1/3), 4(1/4) and 5(1/5) to make the result a whole number, isSolution
Take only fractional parts and add them , 1/2 + 1/3 + 1/4 + 1/5 = 77/60 Nearest whole number will be 2, i.e 120/60 2 – 77/60 = 43/60 So, the answer would be option d) 43/60

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).
