Question
Quantity-I: 'E' can do 40% of work in 32 hours. Find
the value of 'Y' if the time taken by him to complete the whole work is 'Y' hours. Quantity-II: What is the value of 'X' in the given series: 67, 69, 72, 77, 84, 'X'? In the question, two Quantities I and II are given. You have to solve both the Quantity to establish the correct relation between Quantity-I and Quantity-II and choose the correct option.Solution
ATQ, Quantity I: Y = (32/40) × 100 = 80 So, Quantity I = 80 Quantity II: The given series is: number + consecutive prime numbers starting from '2'. 67 + 2 = 69 69 + 3 = 72 72 + 5 = 77 77 + 7 = 84 84 + 11 = 95 So, X = 95 So, Quantity II = 95 So, Quantity I < Quantity II
