gladu [14]

Answer: The right  answer is 2

Step-by-step explanation:

  1. Write out the expression

T1; a = 0.3 ------------ (I)

T8; ar^7 = 38.4 ------------ (ii)

Substituting for 'a' in the second equation, we have;

0.3r^7 = 38.4

0.3r^7 = 38.4

Divide both sides by 0.3

r^7 = 38.4/0.3

r^7 = 128

r = (128)^1/7

r = 2

LenaWriter [7]

Answer:

Rs. 23520

Step-by-step explanation:

Given that :

At 12% profit ; sales price = 18,816

At (12 + 3)% profit ; sales price = x

Hence,

0.12 = 18,816

0.15 = x

Cross multiply ;

0.12x = 0.15 * 18816

0.12x = 2822.4

x = 2822.4 / 0.12

x = 23520

Hence, sales price for a 3% increaa in profit should be Rs. 23520
