Richa's age = R yrs honey's age = 5 * R yrs

Thomas's age = 2 * R yrs

Richa's age = Thomas's age - 12 yrs R = 2 * R - 12 => R = 12 years Honey is 5 * 12 = 60 yrs old ========================= question 2

number of men = M number of women = W = 4/5 * M total population = 1800 = M + W 1800 = M + 4/5 * M 1800 = M * [ 1 + 4/5 ] = M * 9 / 5

A1: Let the age of Richa be x years. Then, Age of Thomas = (x+12)years .....(i) According to question, Age of Thomas is of twice age of that of Richa. Thus, Age of Thomas = 2x. .....(ii) Now, ⇒2x=x+12 [From equation (i) and (ii)] ⇒2x-x=12 ⇒x=12 Therefore, Age of Richa = 12 years Age of Honey = 5*12 = 60 years. Ans

A2: Let the no. of men in the village be x. Then, No. of women = 4x/5 Total population = 1800 Therefore, ⇒x+4x/5=1800 ⇒(5x+4x)/5=1800 ⇒9x/5=1800 ⇒9x=1800*5 ⇒9x=9000 ⇒x=9000/9 ⇒x=1000 Therefore, No. of males = x = 1000 No. of females = 4x/5 = 4*1000/5 = 800 Ans.
