(x + y) യുടെ 50% = (x - y) യുടെ 75% ആണെങ്കിൽ, y യുടെ എത്ര ശതമാനം x ന് തുല്യമാണ്?

A400%

B100%

C200%

D500%

Answer:

D. 500%

Read Explanation:

(x + y) യുടെ 50% = (x - y) യുടെ 75% 50(x + y) = 75(x - y) 50x + 50y = 75x - 75y 50y + 75y = 75x -50x 125y = 25x x = 5y ശതമാനം = (ലഭിച്ച മൂല്യം/ആകെ മൂല്യം) × 100 = (x/y) × 100 = (5y/y) × 100 = 500%
