Answer 1

Answer:

16%

Step-by-step explanation:

Explanation:

Let cost of each cell phone = Rs.100 & Sale = 100 phones.

Money receipt = Rs.(100 x 100) = Rs.10,000

New cost per cellphone = Rs.120 and New sale = 70 phones

New Money Receipt = Rs.(70 x 120) = Rs.8400

Then the effect of sales = decrease in money receipt =

160010000 x 100 = 16%.

→ Price of a mobile is decrease by = 30% .

then,

→ New price of a mobile = (100 * 70)/100 = Rs.70

and,

→ sales was increased by = 20% .

then,

→ New sales = (100 * 120)/100 = 120 mobiles.

therefore,

→ Total money shop gets now = 120 * 70 = Rs.8400 .

hence,

→ Decreased in the sell of shop = 10000 - 8400 = Rs.1600

→ % Decreased = (1600 * 100) / 10000 = 16% (Ans.) (a)
