Let the number be a
According to question,
2/5 of 1/5 of 1/3 of a = 20
=> 2/5 of 1/5 of a/3 = 20
=> 2/5 of 1/5×a/3 = 20
=> 2/5 of a/15 = 20
=> 2/5 × a/15 = 20
=> 2a/75 = 20
=> a = 20× 75 /2
=> a = 750
Required number = 750
Verification :-
1/3 of 750 = 750 /3 = 250
1/5 of 250 = 250 /5 = 50
2/5 of 50 = 2 × 50 /5 = 2 × 10 = 20
Hence verified.
