1) c – 157000

2) b – Dalal Street Journal

3) a – decreases by 50%

4) b – Dalal Street Journal

5) c – increased by Rs 466


SOLUTION

1) Total circulation in 1988 = 40000 + 60000 + 30000 + 27000 = 157000

2) Percentage growth for the business India during 1987-89 = (69 – 45) / 45 * 100% = 53.3%
Percentage growth for the Dalal Street Journal during 1987-89 = (49 – 18) / 18 * 100% = 172%
Percentage growth for the Business World during 1987-89 = (32 – 25) / 25 * 100% = 28%
Percentage growth for the Fortune during 1987-89 = (31 – 20) / 20 * 100% = 55%

MAXIMUM is for Dalal Street Journal

3) In 1989, advertisement tariff for FI in 1989 = Rs 28000
According to condition, advertisement tariff for 1989 = Rs 14000
So, cost of advertisement will be decreased and percentage decrease per thousand copies
= [(28000 – 31000)/1000] – [(14000/31000) – 1000] / [(28000 – 31000)/1000] = 50%

4) Advertisement cost per 100 copies is given below

Dalal Street Journal = (14000/40000)*1000 = Rs 350
Business World= (20000/30000)*1000 = Rs 666
Fortune India= (17000/27000)*1000 =Rs 629
Business India= (30000/60000)*1000 =Rs 500

LOWEST is for Dalal Street Journal.

5) Advertising Cost per 1000 copies of Business World in 1987
= (5000/25000)/1000 = Rs 200

 Advertising Cost per 1000 copies of Business World in 1988
= (20000/30000)/1000 = Rs 666

Hence, cost increased by Rs 466
