Study the following information to answer the questions given below :
‘A * B’ means ‘multiply A by B.
‘A @ B’ means ‘subtract B from A’.
‘A $ B’ means ‘add B to A’.
‘A # B’ means ‘divide A by B’
The area of a circle is computed by multiplying the square of its radius by 22/7. What will be the total area of 14 circles, each with the same radius of ‘r’ cms. ?
(A) 22 * r *7 * r # 14
(B) 22 # 14 * r * r
(C) 44*r*r # 7
Total area of 14 circles, each with the same radius of ‘r’ cms = $$14\times\frac{22}{7} r^2$$
(A) : 22 * r *7 * r # 14
=> $$22\times r\times7\times r\div14=\frac{154r^2}{14}=11r^2$$
(B) : 22 # 14 * r * r
=> $$22\div14\times r\times r=\frac{11r^2}{7}$$
(C) : 44*r*r # 7
=> $$44\times r\times r\div7=\frac{44r^2}{7}$$
Thus, none of the statements is correct.
