Question

Ram is travelling from city A to city B. He has travelled 180 km so far. If the ratio between distance travelled to distance left is 6 : 3. Find the distance yet to be travelled.

• A. 100 km
• B. 60 km
• C. 90 km
• D. 120 km

Answer 1

The correct option is C 90 km

Distance travelled = 180 km.
Ratio between distance travelled to distance left = $\frac{6}{3}$
Multiplying both numerator and denominator by 30,
Ratio = $\frac{6}{3}$ × $\frac{30}{30}$ = $\frac{180}{90}$
∴ Distance yet to be travelled = 90 km
