a اور b کی تنخواہ کا تناسب 9:4 ہے اگر تنخواہ میں 15% اضافہ ہوتا ہے تو اس کی کل تنخواہ 5175 روپے بنتی ہے۔ b کی تنخواہ کیا ہے؟

2000

4000

4500

None of these

Ratio of their salary = 9:4

Let salary of A = 9x

and of B = 4x

when salary of A increase we get,

Salary of A = 9x (1 + 15/100) = 5175

9x (115/100) = 5175

9x = 5175 * 100 / 115

9x = 4500

x = 500

So salary of B = 4x

4(500) = 2000

Therefore salary of B is Rs. 2000.
