Answer» Let age of Beens be xThen age of her mother =(x + 30) As per given conditionx + (x + 30)/3 = 26 Take LCM 3x + x + 30 = 26*34x + 30 = 784x = 78 - 30 = 48x = 48/4 = 12 Therefore, age of Beena = 12 years Let age of beena's be x.......and mother be x+30A.C to question.....x+1/3(x+30)=26[as sum of Beena and one third of his mother age is 26]x+1/3x+1/3×30=x+1/3x+10=264x/3+10=264x/3=26-10=16x=16×3/4=4×3=12 This one is more easier...... |
