### GATE CSE 2015 Set 2

A half adder is implemented with $XOR$ and $AND$ gates. A full adder is implemented with two half adders and one $OR$ gate. The propagation delay of an $XOR$ gate is twice that of an $AND/OR$ gate. The propagation delay of an $AND/OR$ gate is $1.2$ microseconds. A $4$-bit ripple-carry binary adder is implemented by using four full adders. The total propagation time of this $4$-bit binary adder in microseconds is____________ .

Correct Answer is 19.2
