Solution

## The correct option is A 10 Number of combatants that lost all of four body parts = 100 - (Sum of combatants who did not loose an eye or an ear or an arm or a leg) Percent of combatants who did not loose an eye = 30 Percent of combatants who did not loose an ear = 20 Percent of combatants who did not loose an arm = 25 Percent of combatants who did not loose a leg = 15 Minimum value of x = 100 - (30 + 20 + 25 +15) = 100 - 90 = 10
