Answer
Solution
Correct Answer Is : 322
Solution Is :
If 5x + 9y = 5 and 125x + 729y = 120 then the value of the product of x and y is

a) 135
b) 1/135
c) 1/9
d) 45



Answer
Solution
Correct Answer Is : 1/135
Solution Is : 5x +9y = 5 ...(i)
125x3+ 729y3=120 ...(ii)
Now cube both sides of equation (i), we get
⇒ (5x + 9y)3= (5)3
⇒125x3 + 729y3+135xy(5x +9y)=125
⇒ 125x3 + 729y3 +135xy *5 =125
Now, put the value of equation (i)
120 + 135 xy × 5 = 125
⇒ 135 × 5xy = 125 - 120
⇒135 × 5xy = 5 ⇒
xy=(5/(135*5))=1/135
If p = 99 then, the value of p(p2 + 3p + 3) is :

a) 999999
b) 988899
c) 989898
d) 998889



Answer
Solution
Correct Answer Is : 999999
Solution Is : Given P = 99
then P(P2 + 3P + 3)
= P((P + 1)2+ P + 2)
= 99 ((99 + 1)2 + 101)
= 99 × (10000 + 101)
= 999999
