Answer 2

Hey there! ☺☻☺

$Principal = P = Rs. 21000\\Rate = R = 6\%\\Time = T = ?\\S.I = Rs. 5040\\\\We \ know,\\S.I = \frac{P\times R\times T}{100}\\\\5040=\frac{21000 \times 6 \times T}{100}\\\\\frac{5040\times 100}{21000\times 6} = T\\\\T = \frac{504}{126}\\\\\boxed{\boxed{\bold{T = 4 \ years}}}$
