The figure, not drawn to scale, is made up of 3 different triangles T, U and V. 15% of triangle T and 35% of triangle V is shaded. The shaded area of T is the same as the shaded area of V. What fraction of the figure is shaded if 25% of Triangle U is shaded?

Unshaded area of T	Shaded area of T	Unshaded area of V	Shaded area of V
17x7	3x7	13x3	7x3
119 u	21 u	39 u	21 u

15% = ¹⁵₁₀₀ = ³₂₀
35% = ³⁵₁₀₀ = ⁷₂₀
25% = ²⁵₁₀₀ = ¹₄
The shaded area of T is the same as the shaded area of V.

Make the LCM of the shaded area of T and shaded area of V the same.
LCM of 3 and 7 = 21

¹₄ of U is shaded
= Shaded area of T + Shaded area of V
= 21 u + 21 u
= 42 u

Fraction of U that is unshaded 
= 1 - ¹₄
= ³₄ 

¹₄ of U = 42 u
³₄ of U = 3 x 42 u = 126 u

Fraction of the figure that is shaded if 25% of Triangle U is shaded
= ^{42 + 42}_{119 + 126 + 39 + 42 + 42}
= ⁸⁴₃₆₈
= ²¹₉₂

Answer(s): ²¹₉₂
