Answer 1

Answer:

assume total eggs X

cost price = (X/3)*5

selling price= (X/5)*12

cp-sp= 143

solve above equation we get X=195

Answer 2

Step-by-step explanation:

according to question :-

CP of 3 eggs = 5

CP of 1 egg = 5*3 = 1.66

SP of 5 eggs = 12

SP of 1 egg = 12/5 = 2.40

gain for 1 egg = 2.40-1.66 = 0.74

so

if

0.74 = 1 egg

143 = 1/0.74*143 = 195 eggs
