If A+B = 76, A - B = 38, Then A÷B = ?
Solution
Correct Answer: Option A
দেওয়া আছে,
A+B = 76 ...... (i)
A - B = 38 ...... (ii)
এখন, (i)÷(ii) হতে পাই,
(A+B)/(A-B) = 76/38
⇒ 2A/2B = (76+38)/(76-38) [যোজন-বিয়োজন করে]
⇒ A/B = 114/38
⇒ A/B = 3
A+B = 76 ...... (i)
A - B = 38 ...... (ii)
এখন, (i)÷(ii) হতে পাই,
(A+B)/(A-B) = 76/38
⇒ 2A/2B = (76+38)/(76-38) [যোজন-বিয়োজন করে]
⇒ A/B = 114/38
⇒ A/B = 3
