5.Cannot be determinedAnswer –**2.26%**

**Explanation :**

SP = CP*135/100

SP = MP*90/100

CP = MP*90/135

Customer SP = MP*84/100

MP*84/100 = MP*90/135*(100+y)/100

100+Y = 126

Y = 26%**In an examination, ratio of number of students who passed to number of students who failed is 5:2.

**Explanation :**

5x+y/2x+10-y = 7:3

and 2x+10-y- 2x =5

y =5

then x =20

total = (5+2)*20 = 140**The probability that Vijay will join IIT is 2/7 and that he will join NIT is 3/5.Find that probability that he will join either IIT or NIT?**
