Question 23
The percent that represents the shaded region in the figure, is (a) 36 % (b) 64 % (c) 27 % (d) 48 %
Given, total parts = 10×10=100 ∵ Shaded parts = 36 ∴ Per cent of shaded parts =36100×100%=36% Hence, the shaded region is 36 %
Question 22
The per cent that represents the unshaded region in the figure, is (a) 75 % (b) 50 % (c) 40 % (d) 60 %
In the given figure, ∠CAE=84∘. If ∠B:∠C=3 : 4, then ∠B = ___ and ∠C = ___,
