Answer 1

Answer:

a) 1200%

b) 7%

Step-by-step explanation:

a) 12 PENS (1 DOZEN) ARE BOUGHT FOR RS. 18

SO, 1 pen would cost Rs. 1.5

PROFIT PERCENTAGE= SP/CP×100

18/1.5×100=1200%

b) SIMPLE INTEREST FOR 1 YEAR WOULD BE

1750/5=350

SO, IT WOULD BE

$350 = 5000 \times rate \div 100 \times 1year$

$350 \div 5000 \times 100 = rate$

SO, RATE WOULD BE 7%
