A number theory problem by Soumya Mitra

Number Theory Level 1

Bridget bakes 48 loaves of bread for her bakery. She sells half of them in the morning for $2:50 each. In the afternoon she sells two thirds of what she has left, and because they are not fresh, she charges only half price. In the late afternoon she sells the remaining loaves at a dollar each. Each loaf costs $0:75 for her to make. In dollars, what is her pro t for the day?

Half of Her bake loaves of bread is 24 @ $2:50=60, then 2/3 of the remaining is 16@$1.25=20 And the remaining is 8@$1=8, so total of $88 less the cost which is 48 loaves @$.75 = 36, So $88-36= $52.

IT IS TOO SIMPLE JUST USE THE NO. THEORY GETTING THE RATE IN WHICH THE EACH LOAF IS SOLD AND THE NO. OF LOAF SOLD AT A PARTICULAR TYM WE CAN GET THEANSWER THAT IS 52

Half the loaves means 24 are sold at 2.5 $ each. Two- thirds of remaining means 2/3 of 24 loaves i.e 16. So she sold 16 loaves for half the price i.e 1.25 $ each. Now remaining 8 are sold at $ 1 each. 24* into 2.5=60. 16 into 1.25=20. 8 into 1=8. Adding up we get 88$. She spends $0.75 to make a loaf. Therefore 0.75 *into 48=36. Profit=S.P- C.P =88- 36 =52$. She made a profit of 52$.
