Question

if A Kaa 30% B ke 40% me add kiya jaata h to ans. B kaa 80% aata h to A kaa kitna percent B Jai?

Answer 1

according to question ,

30% of A + 40% of B = 80% of B

30/ 100 × A + 40 / 100× B = 80/ 100 × B

0.3 A + 0.4 B = 0.8 B

0.3A = 0.8B - 0.4B

0.3A = 0.4 B

0.3 / 0.4 A = B

0.75 A = B

75% of A = B ( 100%)

therefore , 75 % of A = B
