mina had 20% less hair clips than anne.caili had 20% more hair clips than mina.express caili's hair clips as a percentage of anne's hair clips

Take Anne's hairclip as 100%. Mina's hairclips will be 80%. Caili is 20% more than Mina - so it is 80% + 16% = 96%

Thus Caili's hairclips as a percentage if Anne's is 96%

marina has 200 more books than ethel.marina gives 60% of his books to ethel.ethel then gives 25% of her books back to marina .in the end ,ethel has 200 more books than marina.how many books does marina have at first?

At first: M has 10U + 200, E has 10U
Step 1 - M give E 60%: M has 4U + 80, E has 16U + 120
Step 2 - E give M 25%: M has 8U + 110, E has 12U + 90

12U + 90 - 200 = 8U + 110
4U = 310 - 90 = 220
U = 55

Initially Marina has 550 + 200 = 750 books
