Question 1
1 / -0

In a battle 70% of combatants lost one eye , 80% an ear , 75% an arm , 85% a leg ,x% lose all the four limbs. The minimum value of x is :

A
15

B
12

C
11

D
10

Solution

Given that percentage of combatants who lost one eye=70%, an ear=80% and an arm =75% and a leg =85%

Hence we get percentage of combatants who lost one eye and one ear =(70%+80%)-100%=50%

percentage of combatants who lost one eye one ear and one arm =(50%+75%)-100%=25%

Similarly percentage of combatants who lost one eye one ear one arm and one leg =(25%+85%)-100%=10%

Hence we get percentage of combatants who lost all 4 limbs =10%

Hence if x% represent the percentage of combatants who lost all 4 limbs we get minimum value of x=10
