Cecilia compra un saco de papas y lo lleva al mercado para vender. En la primera hora vende un cuarto del saco a S/ 1,50 el kilo. Luego, en la segunda hora vende las dos terceras partes del resto a S/ 1,20, quedándole 24 kilos. Si el saco de papas le costó S/98,90, ¿cuánto ganó si siguió vendiendo lo que quedó a S/ 1,10 el kilo?
Answers
Given : Cecilia buys a sack of potatoes and takes it to the market to sell.
In the first hour she sells a quarter of the bag for S / 1.50 per kilo.
Then, in the second hour, she sells two-thirds of the rest of it for S / 1.20, leaving her with 24 kilos.
she kept selling what was left at S / 1.10 per kilo
the bag of potatoes cost her S / 98.90,
To Find : how much did she earn
Solution:
bag of potatoes cost her S / 98.90,
=> CP = 98.90 S
In the first hour she sells a quarter of the bag = (1/4) * 100 = 25 kg
S 1.50 per kilo. Hence SP = 1.5 * 25 = 37.5 S
Rest = 100 -- 25 = 75 kg
in the second hour, she sells two-thirds of the rest of it
= (2/3) 75 = 50 kg
S / 1.20 per kilo SP = 1.2 * 50 = 60 S
Remaining = 100 - 25 - 50 = 25 kg
S / 1.10 per kilo => SP = 1.1 * 25 = 27.5 S
Total SP = 37.5 + 60 + 27.5 = 125 S
CP = 98.90 S
Profit = 125 - 98.90 = 26.1 S
she earned = 26.1 S
