The following ratios are given: a : b = 2 : 3 b : c = 4 : 5 c : d = 3 : 2 d : e = 5 : 4 What is the value of the ratio a : e?
निम्नलिखित अनुपात (Ratio) दिए गए हैं: a : b = 2 : 3 b : c = 4 : 5 c : d = 3 : 2 d : e = 5 : 4 अनुपात a : e का मान ज्ञात कीजिए।
Answer और ExplanationAnswer and explanation
Answer: (C) 1 : 1
a : e = ab × bc × cd × de
= 23 × 45 × 32 × 54
b, c, d कट जाते हैं, तो 2 × 4 × 3 × 53 × 5 × 2 × 4 = 1
✓
a : e = 1 : 1।
a : e = ab × bc × cd × de
= 23 × 45 × 32 × 54
Cancelling b, c, d, we get 2 × 4 × 3 × 53 × 5 × 2 × 4 = 1
✓
a : e = 1 : 1.
