Answer: (B) 5,580

The formula for the sum of the first n terms of an arithmetic progression is

S_{n} = \frac{n}{2} (a + a n)

\frac{30}{2} (12 + 12 * 30)

= 15*(12+360) = 15 * 372 = 5580

\frac{40 * 40}{100}

% = -

\frac{1600}{100}

% = -16%

(D) 600
(D) 600

Answer: (C) 500
Answer: (C) 500

100 * 100% + 200 * 200% =

100 \times \frac{100}{100} + 200 \times \frac{200}{100}

\frac{10000}{100} + \frac{40000}{100}

= 100 + 400 = 500

100 * 100% + 200 * 200% =

100 \times \frac{100}{100} + 200 \times \frac{200}{100}

\frac{10000}{100} + \frac{40000}{100}
