7411IC contains 14 pins. out of which 1 is +vcc and 1 is gnd .now left 12 pins. one AND gate requires 3 pins (2 for i/p and 1 for o/p).so there should be 4 AND gates. 2 on one side and 2 on other side.

54LS11/DM54LS11/DM74LS11 / 74HC11 / 74HCT11 / DM74LS11 : Triple 3-Input AND Gates

7411 General Description

This device contains three independent gates each of which performs the logic AND function.

7411 Absolute Maximum Ratings:

* Supply Voltage: 7V
* Input Voltage: 7V
* Operating Free Air Temperature Range : 0 C to +70 C
* Storage Temperature Range: -65 C to +150 C

Triple input...one output. So 3 AND gates.

We required four and gates but your answer is three gates why?

This is wrong answer. It has 4 gate. I know it practically.

7411 IC is 3 input and gate. Check for the pin diagram you all know about it.
