दिया गया है:

4200 का 30% + 2400 का 35% = 4200 का x%

प्रयुक्त सूत्र:

प्रतिशत की गणना: N का P% = (P x N) / 100

गणना:

4200 का 30% = (30 × 4200) / 100

⇒ 4200 का 30% = 1260

2400 का 35% = (35 × 2400) / 100

⇒ 2400 का 35% = 840

अब, हम इन मानों को जोड़ते हैं:

1260 + 840 = 2100

इसे 4200 के x% के बराबर सेट करते हैं:

4200 का x% = (x × 4200) / 100

⇒ (x × 4200) / 100 = 2100

⇒ x × 4200 = 210000

⇒ x = 210000 / 4200

⇒ x = 50

∴ x का अभीष्ट मान 50 है।
