Question

Answer

Egg seller finally had 45 eggs. He had 45 + 5 = 50 eggs before giving his friend. 

He had 50 -15 = 35 eggs before buying 15 eggs.

35 eggs represent ( 1- 0.3 ) = 0.7 of the egges he owned in the beginning.

Number of eggs he had at first = 35/0.7 = 50

He had 50 eggs at first.

 

Check: 50 * 0.7 = 35

35 + 15 – 5 = 45          (Checked)

That is one terrible question though. The first thing I thought was, “How do you break 0.3 of some eggs?” Nobody says that! You can say 3/10 of the eggs, or 30% of the eggs, but 0.3 of the eggs is just… wrong (even though they are mathematically equivalent).

Lol… it took me a few seconds to process 0.3 too.  But I think the examiner is just trying to test understanding of ratios.  Bad test.
