Let the price of Uniform be U Taka
atq,
12Month = 30000+U………….(i)
9Month = 22000+U ………….(ii)
From Equation (i)9 - (ii)12
We get , 270000+ 9U - 264000 - 12U = 0 so, 3U = 6000 so, U = 2000 Taka
So, Required price of the Uniform = 2000 Taka
Price Ratio of (H : C) = (5 : 3) = (106)
Total Cost of 4H & 6C = (4 x 5 + 6 x 3) = 38 units
According to the Question,
38 units = 1900 Tk
⇒ 5 units 250 Tk (Ans)
Total Amount = 180 units
Wife gets = of 180 = 72 units
Son gets = of 108 27 units
Donated = 2/9 of 81 = 18 units
According to the Question,
180 units 2000000 Tk
⇒ 18 units=200000 Tk (Ans)
Ratio of (1 : P) = (432 : 1200) = (9 : 25)
According to the Question,
(9 × 100) = 25n²
⇒ n² = 36
⇒ n = 6% (Ans)
According to the Question,
a√2 = 12√2
⇒ a = 12 cm
So, Perimeter of Square = (4 × 12 ) = 48 cm
So, Each sides of Triangle = of 48 = 16 cm
Area of Triangle = × 16 × 8√3 = 64√3 (Ans)
