Question

In seminarthe no. Of participate in english ,maths ,science are 175,140,105 respectively find the minimum no. Of rooms

Answer 1

To find the minimum number of rooms, we need to find the HCF of 175,140, and 105

So,

175 = 5 × 5 × 7

140 = 7 × 2 × 2 × 5

105 = 7 × 5 × 3

HCF = 7 × 5 = 35

$\green{\mathfrak{35\:rooms}}$
