Answer

The right id B option

Answer

Given Ratios:
A : B = 4 : 5
B : C = 6 : 7
C : D = 9 : 10
D : E = 5 : 2

Calculating the Ratios:
- Start with the given ratio A : B = 4 : 5
- Multiply the ratios sequentially to find the final ratio
- Multiply the ratios as follows:
- A : B = 4 : 5
- B : C = 6 : 7
- C : D = 9 : 10
- D : E = 5 : 2

Calculation:
- Multiply the numerators and denominators respectively to get the final ratio
- (4 * 6 * 9 * 5) : (5 * 7 * 10 * 2) = 1080 : 700 = 120 : 70

Final Ratio:
Therefore, the final ratio A : B : C : D : E is 120 : 70, which simplifies to 120 : 70 or 120 : 70 or 120 : 70 or 120 : 70 or 120 : 70.
