On squaring,

⇒ x2 = 6 + x
⇒ x2 – x – 6 = 0
⇒ x2 – 3x + 2x – 6 = 0
⇒ x (x – 3) + 2 (x –3) = 0

From 9.00 AM to 2.00 PM, the temperature rose at a constant rate from 21ºC to 36ºC. What was the temperature at noon ?       (SSC CHSL 2012)
Detailed Solution for SSC CGL Previous Year Questions: Simplification and Square & Cube Root- 3 - Question 17

Time difference between 9.00 A.M & 2.00 P.M = 5 hours
Temperature difference between 21°C & 36°C = 36 – 21 = 15°C
Now, Time difference between 9.00 A.M & 12.00 Noon = 3 hrs.
In 5 hours 
So, In 3 hours 
So, temperature at noon = 21 + 9 = 30°C

Detailed Solution for SSC CGL Previous Year Questions: Simplification and Square & Cube Root- 3 - Question 28

Let the numbers be x and y.
∴ x (x + y) = 247
and y (x + y) = 114
⇒ x2 + xy = 247 and xy + y2 = 114
On adding;
x2 + xy + xy + y2 = 247 + 114
⇒ x2 + 2xy + y2 = 361
⇒ (x + y)2 = 192 ⇒  x + y = 19
