Flaky aggregate = 3/5 of there's mean dimension.
= (3/5) *{(75+60) /2}.
= (3/5) *(67.5).
= 40.5mm.

An aggregate is said to be flaky if its least dimension is less that 3-5.

That's why we use 3÷5.

If an aggregate is rounded or angular then what value will be use about dimension? Please explain.

Thanks for the correct explanation. @Lalit

Flaky aggregate = 3/5 of the mean dimension.
= (3/5) *{(75+60) /2}.
= (3/5) *(67.5).
= 40.5mm.
