‘B’ is 28 years older than ‘A’. After 12 years from now, the age of ‘B’ will be twice the age of ‘A’. The present age of ‘A’ is :<\/p>\n
[amp_mcq option1=”10 years” option2=”12 years” option3=”30 years” option4=”16 years” correct=”option4″]<\/p>\n
After 12 years from now:
\nAge of A will be A + 12 years.
\nAge of B will be B + 12 years.<\/p>\n
According to the second statement, the age of ‘B’ will be twice the age of ‘A’ after 12 years:
\nB + 12 = 2 * (A + 12) (Equation 2)<\/p>\n
Now, we substitute Equation 1 into Equation 2:
\n(A + 28) + 12 = 2 * (A + 12)
\nA + 40 = 2A + 24<\/p>\n
Now, we solve for A:
\n40 – 24 = 2A – A
\n16 = A<\/p>\n
