a ∶ b = 3 ∶ 4
b ∶ c = 2 ∶ 3
c ∶ d = 5 ∶ 6
वापरलेले सूत्र:
a ∶ b ∶ c ∶ d शोधण्यासाठी, आपल्याला सर्व पदांसाठी एक सामान्य गुणोत्तर शोधावे लागेल.
गणना:
a ∶ b = 3 ∶ 4
b ∶ c = 2 ∶ 3
c ∶ d = 5 ∶ 6
प्रथम, a ∶ b आणि b ∶ c या दोन्ही गुणोत्तरांमध्ये 'b' पद समान करा:
a ∶ b = 3 ∶ 4 = 3 × 2 ∶ 4 × 2 = 6 ∶ 8
b ∶ c = 2 ∶ 3 = 2 × 4 ∶ 3 × 4 = 8 ∶ 12
आता, b ∶ c आणि c ∶ d या दोन्ही गुणोत्तरांमध्ये 'c' पद समान करा:
c ∶ d = 5 ∶ 6 = 5 × 3 ∶ 6 × 3 = 15 ∶ 18
आता, a ∶ b ∶ c ∶ d एकत्र करा:
a ∶ b = 6 ∶ 8
b ∶ c = 8 ∶ 12
c ∶ d = 15 ∶ 18
त्यामुळे, a ∶ b ∶ c ∶ d = 6 ∶ 8 ∶ 12 ∶ 15 ∶ 18
⇒ सरळ स्वरूपात: 15 ∶ 20 ∶ 30 ∶ 36
∴ योग्य उत्तर पर्याय (3) आहे.
