4200-এর 30% + 2400-এর 35% = 4200-এর x%
ব্যবহৃত সূত্র:
শতকরা হিসাব: N-এর P% = (P x N) / 100
গণনা:
4200-এর 30% = (30 x 4200) / 100
⇒ 4200-এর 30% = 1260
2400-এর 35% = (35 x 2400) / 100
⇒ 2400-এর 35% = 840
এখন, আমরা এই মানগুলি যোগ করি:
1260 + 840 = 2100
এটিকে 4200-এর x% এর সমান ধরা যাক:
4200-এর x% = (x x 4200) / 100
⇒ (x x 4200) / 100 = 2100
⇒ x x 4200 = 210000
⇒ x = 210000 / 4200
⇒ x = 50
∴ x-এর মান 50।
