Example 11 What per cent of the adjoining figure is shaded? There are total 3 boxes, Out of which 1 & 1/2 are shaded. Let’s find the percentage shaded Total boxes = 3 Boxes shaded = 1 + 1/2 = (1 Γ— 2 + 1)/2 = (2 + 1)/2 = 3/2 So, Percentage shaded = (π΅π‘œπ‘₯𝑒𝑠 π‘ β„Žπ‘Žπ‘‘π‘’π‘‘)/(π‘‡π‘œπ‘‘π‘Žπ‘™ π‘π‘œπ‘₯𝑒𝑠) Γ— 100% = (3/2)/3 Γ— 100% = 3/(2 Γ— 3) Γ— 100% = 1/2 Γ— 100% = 100/2 % = 50%
