1. If x + 1/x 0, x2 + 1/x2 = 1 and x3 + 1/x3 = 0 , then the value of ( x + 1/x) ^4 is equal to

**Answer** 9

**Solution** (x + 1/x )^4 = (x + 1/x)^3 (x + 1/x)

= (x^3 + 1/ x^3 + 3(x + 1/x ) ) (x + 1/x)

= 3 (x + 1/x)^2

= 3 ( x2 + 1/x2 + 2 )

= 3( 1 + 2 ) = 9

- If principal of Rs. 3000 amounts to 6000 in 2 years on C.I. , then how much it will amount in 4 years ?
