Question

Quantity-I: Determine the lateral surface area of a cube where the length of each edge is 'y'
cm. Here, 'y' represents the smallest two-digit number. Quantity-II: The breadth of a cuboid is 25% less than its length. If the cuboid's length is 20 cm and its height is 6 cm, calculate its lateral surface area.

ATQ, Quantity I smallest two-digit number, y 10 Lateral surface area of cube 4 Edge2 Therefore, required area 4 102 4 100 400 cm2 So, Quantity I 400 cm2 Quantity II Breadth of cuboid 0.75 20 15 cm Lateral surface area of cuboid 2 Length Breadth Height Therefore, required area 2 20 15 6 2 35 6 420 cm2 So, Quantity II 420 cm2 Therefore, Quantity-I lt Quantity-II

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.

A Quantity-I > Quantity-II

B Quantity-I < Quantity-II

C Quantity-I ≥ Quantity-II

D Quantity-1 ≤ Quantity-II

E Quantity-I = Quantity-II or No relation
