Explanation
1. From statement II,
X + y = 18
It is possible only when x = y = 9


2. Data are inadequate


3. Form both statements, Speed of boat in still water =
image001


4. From statement I
Nigam’s marks in Biology= 2 × 42 = 84


5. From Statement I,
Rate = image003
=image005
From statement II,
By using C.I
image007
We get the required rate of interest.


6. From statements I and II, side of the square= √196 = 14 cm.
Circumference of the semi circle = (π + 2) × radius = 7 (π + 2) cm.


7. Data are inadequate.


8. From statement I, Cost price of the article = image009
Gain = Rs. (24000 – 14400)= Rs. 9600
Gain per cent = image011
From statement II,
Cost price = Rs. (24000 – 9600) = Rs. 14400
Hence, profit per cent can be determined.


9. From statement I,
X2 = 9y
Required answer is not possible .
From statement II, 4x – 3x = ?


10. From statement I,
X × image013
X=25
From statement II
Y × image015
Y = 60
X : Y = 25 : 60 = 5 : 12
