Question

sankhyayen 7, 16, 43, aur 79 me prtyek me kon si sankhya jodi jay jisse ki sankhyayen smanupat me ho jay? please guys give me answer quickly.

Answer 1

Maan lo "x" sankhya ko jodne se ye chaaro sankhyayen smanupat mein ho jayegi.

Toh uss hisaab se,

Hum aisa likh sakte hain....

(7 + x)/(16 + x) = (43 + x)/(79 + x)

or, cross multiplication k baad hume kya milega;

553 + 79x + 7x + x² = 688 + 43x + 16x + x²

88x - 59x = 688 - 553

or, 27x = 135.

or, x = 5 [Ans].

12, 21, 48, 84 samanupat mein hain.
