Question

A vendor buys 5 bananas for 20 and sold 6 for 30. Find the profit he incurred. Also, find the profit per cent.
​

Answer 1

Answer:

25℅

Step-by-step explanation:

LCM of 6 and 5 is 30

cp of 5 bananas = ₹20

cp of 1 banana = ₹ 20 / 5

cp of 30 bananas = ₹ 20 × 30 / 5

= ₹120

sp of 6 bananas = ₹ 30

sp of 1 banana = ₹ 30/6

sp of 30 bananas = ₹ 30× 30 / 5

= ₹ 150

Sp > Cp , there is a gain

profit = (₹150- 120) = ₹ 30

profit ℅ = 30×100 / 120 ℅

= 25 ℅

Answer 2

Answer:

LCM OF 6 AND 5 IS 30

CP OF 5 BANANAS=RS.20

CP OF 1 BANANA=RS.20/5

CP OF 30 BANANAS=RS 20×30/5

=RS.120

SP OF 6 BANANAS =RS.30

SP OF 1 BANANA=RS.30/6

SP OF 30 BANANAS=RS.30×30/5

=RS.150

SP>CP,THERE IS A GAIN

PROFIT=(RS 150-120)=RS.30

PROFIT IN %= 30×100/125%

=25%
