Answer 1

Q7) = Part of apple eaten by Ritu = 3 Upon 5
= Part of apple by Somu = 1- part of apple eaten by Ritu
= 1 -3 Upon 5 = 2 Upon 5
= Therefore Somu ate 2 Upon 5 part of the apple
= Since, 3 > 2 Ritu had the longer share.
Diffrence between 2 shares = 3 Upon 5 - 2Upon 5 = 1 Upon 5
Therefore, Ritu's share is larger than the share of Somu by 1 Upon 5.

Q8) Time taken by Michal = 7 Upon 12 hours
Time taken by Vaibhav = 3 Upon 4 hours
3 Upon 4 = 3*3/ 4*3 = 9 Upon 12
And 7 Upon 12,
= Since, 9 > 7
= Vaibhav worked longer
Diffrence = 9 Upon 12 - 7 Upon 17 = 2 Upon 12 = 1 Upon 6 hours.
Answer = 1 Upon 6 hours.
