You have to decide whether the data provided in all the three statements are sufficient to answer the question. Read all the statements and give answer –Solution
From (II), Let the mother’s age be x and daughter’s age be (x )/4. From (I) &(II), x - (x )/4 = 45 (3x )/4 = 45 ∴x = 60 years. From (II) & (III), x + (x )/4 = 75 (5x )/4 = 75 ∴x = 60 years. From (I) & (III), x-y = 45 and x+y = 75 By solving will get the value of x i.e. the answer.
