Answer 1

Your answer is 3.8%..

s.p.=27.50
profit=10%

so,. 10%of 27.50=10/100×27.50=2.75

.°. c.p. = 27.50-2.75= 24.75

now, if s.p. = 25.75

and, s.p. - c.p. = 25.75 - 24.75 = 1

that it is +ve, so here is profit...

and, profit % is given by,
let, profit% be X

1 = X/100 × 25.75

X = 100/25.75

X = 3.8%

is the required ans....

Answer 2

SP = 27.50 WHEN PROFIT = 10 PERCENT

CP = ( 100 ÷ 100 + PROFIT PERCENT )× SP

= ( 100 ÷ 100 + 10 ) × 27.50

= (100 ÷ 1000 ) × 27.50

= ( 1 ÷ 10 ) × 27.50

= (27.50 ÷ 10 )

CP = 275.0

PROFIT PERCENT = ( PROFIT × 100 ÷ CP)

= ( 10 × 100 ÷ 275 )

= ( 1000 ÷ 275 )

= .275
