Question : Two equal tangents PA and PB are drawn from an external point P on a circle with centre O. What is the length of each tangent, if P is 12 cm from the centres and the angle between the tangents is 120$^\circ$?

Option 1: 24 cm

Option 2: 6 cm

Option 3: 8 cm

Option 4: cannot be determined

Team Careers360 25th Jan, 2024

Correct Answer: 6 cm


Solution :
Given, $OP = 12$ cm and $\angle APB=120^\circ$
In $\triangle OPA$ and $\triangle OPB$,
$PA=PB$ (equal tangents)
$\angle OAP=\angle OBP=90^\circ$ (tangent is perpendicular to the radius at its point of contact)
$OP=OP$ (common side)
So, $\triangle OPA$ $\cong$ $\triangle OPB$ 
So, $\angle APO=\frac{120^\circ}{2}=60^\circ$
Now,

Question : If the price of apples increases from Rs. 80 per kg to Rs. 100 per kg, by what percentage should the consumption of apples decrease so that the expenditure remains the same?

Option 1: 25%

Option 2: 22%

Option 3: 20%

Option 4: 18%

Team Careers360 22nd Jan, 2024

Correct Answer: 20%


Solution : Here the expenditure is the same.
So, price will be inversely proportional to consumption.
Price increases from 80 to 100.
therefore, the quantity decreases from 100 to 80.
Reduction in the quantity $=\frac{100 – 80}{100}\times 100=\frac{20}{100}\times 100 = 20$%
Hence, the correct answer is 20%.
