ধরি, Ronald এর আছে R টাকা Howard এর আছে 3R টাকা Howard, Ronald কে 50 টাকা দিয়ে দিলে Howard এর টাকা হয় = (3R - 50) টাকা Ronald এর টাকা হয় = (R + 50) টাকা তখন, 3(3R - 50) = (R + 50) ⇒ 3(3R) - 150 = (R + 50) ⇒ 9R - R = 200 ⇒ 8R = 200 ∴ R = 25 ∴ Ronald এর আছে 25 টাকা ∴ Howard এর আছে (3 × 25) = 75 টাকা ∴ তাদের আছে = (25 + 75) = 100 টাকাRelated questions
