Question

The ratio of Alpha’s weight to Beta’s weight is 6:7. If Alpha’s weight is 84kg, How much does Beta weigh?

• A. 92 kg
• B. 96 kg
• C. 98 kg
• D. 94 kg

Answer 1

The correct option is C

98 kg

Let Alpha's weight be 6x and Beta's weight be 7x

Given : 6x = 84

$\Rightarrow x=\frac{84}{6}=14$

$\therefore$ Beta's weight = $x=7\times 14=98$ kg
