1.	If Kavita is 70% more efficient than Savita and 50% less efficient than Babita, Savita is what percent less efficient than Babita?1). 29%2). 71%3). 96%4). 120%
Answer» Kavita’s EFFICIENCY = (100 + 70)% of Savita’s efficiency = 1.7 × Savita’s efficiency Also, Kavita’s efficiency = (100 – 50)% of Babita’s efficiency = 0.5 × Babita’s efficiency Hence, ⇒ 1.7 × Savita’s efficiency = 0.5 × Babita’s efficiency ⇒ Savita’s efficiency = (0.5/1.7) × Babita’s efficiency ⇒ Savita’s efficiency = 0.29 × Babita’s efficiency ⇒ Savita’s efficiency = (1 - 0.71) × Babita’s efficiency ⇒ Savita’s efficiency = (100 – 71)% × Babita’s efficiency ∴ Savita is 71% LESS efficient than Babita.

If Kavita is 70% more efficient than Savita and 50% less efficient than Babita, Savita is what percent less efficient than Babita?1). 29%2). 71%3). 96%4). 120%

Answer»

Kavita’s EFFICIENCY = (100 + 70)% of Savita’s efficiency = 1.7 × Savita’s efficiency

Also,

Kavita’s efficiency = (100 – 50)% of Babita’s efficiency = 0.5 × Babita’s efficiency

Hence,

⇒ 1.7 × Savita’s efficiency = 0.5 × Babita’s efficiency

⇒ Savita’s efficiency = (0.5/1.7) × Babita’s efficiency

⇒ Savita’s efficiency = 0.29 × Babita’s efficiency

⇒ Savita’s efficiency = (1 - 0.71) × Babita’s efficiency

⇒ Savita’s efficiency = (100 – 71)% × Babita’s efficiency

∴ Savita is 71% LESS efficient than Babita.
