3

% of the rest. Find the total number of mangoes bought by him initially,

if he still has 240 mangoes with him.​

Answer 1

Answer:

400

Step-by-step explanation:

let total mangoes be = 100 %

sold=331/3% of 90% = 1/3* 90% = 30%

remaining= 90 - 30 = 60%

60% = 240 => 1% = 4

100% = 4×100 = 400

Answer 2

Answer:

400

Step-by-step explanation:

Let the total number of mangoes be X.

10% were rotten. So remaining mangoes = 0.9X .

He sold remaining 33 1/3 % of the rest. 33 1/3 is 1/3 of 100. So basically he sold 1/3 of 0.9X. So he is left with 2/3 of 0.9X.

Now, he has 240 mangoes still, so

2/3 x 0.9 X = 240

X = (240 x 3)/ (0.9 x 2) = 720/ 1.8 = 400

So, he had 400 mangoes.
