Question : The radii of the two circles are 11 cm and 3 cm. The distance between their centres is 17 cm. What is the length of the direct common tangent?
Option 1: 12 cm
Option 2: 14 cm
Option 3: 16 cm
Option 4: 15 cm
Correct Answer: 15 cm
Solution : The radii of two circles are 11 cm and 3 cm. The distance between their centres is 17 cm. Length of the direct common tangent of two circles = $\sqrt{D^2-({r_{1}}-r{_{2}})^2}$ D = Distance between their centres $r{_{1}}$ = radius of the bigger circle $r{_{2}}$
Question : In an examination, the average marks obtained by the girls of a class is 85 and the average marks obtained by the boys of the same class is 87. If the girls and boys are in the ratio of 4 : 5, the average marks of the whole class (approximately) are closest to:

Option 4: 86.5
Correct Answer: 86.1
Solution : Given: Ratio of girls : boys = 4 : 5 Average marks obtained by the girls = 85 Average marks obtained by the boys = 87 Required average $=\frac{(4×85)+(5×87)}{4+5}= \frac{340 + 435}{9}= \frac{775}{9} = 86.1$ Hence, the correct answer is 86.1.
