If A and B are in the ratio 4:5 and the difference of their squares is 81, what is the value of A?

a) 36
b) 15
c) 45
d) 12



Answer
Solution
Correct Answer Is : 12
Solution Is :
Ratio Now , B2-A2=81 A/B =4/5
⇒ B/A =5/4.
Squaring both sides , we get
⇒B2/A2 =25/16.
Both sides subtract 1
=⇒(B2-A2)/A2 =(25-16)/16 =9/16
⇒81/A2 =9/16
⇒ A2 =16*9 ⇒ A=12

b) Rs. 1200
c) Rs. 3600
d) Rs. 4800



Answer
Solution
Correct Answer Is : Rs. 3600
Solution Is : Ratio of equivalent capitals of A,B and C for 1
month = (16000 * 3 + 11000 * 9) : ( 12000 *3 + 17000 *9): (21000 *6)= (48000 + 99000) : ( 36000 + 153000) : 126000 =
147000:189000 :126000 = 49: 63 : 42 = 7: 9 : 6 .
Sum of ratios +7+9+6 =22.
Therefore required difference =Rs.((9-6)/22) * 26400) = Rs. (3* 26400)/22 =Rs.3600.

=k(x2+4x2+9x2)=14kx2
=(14*5184)/36 =Rs.2016
Therefore, Loss= 5184-2016 =Rs.3168
