Answer: (1) Rs. 5, 700

Explanation:-
Cost price of a mobile phone = Rs. 8, 000
A shopkeeper reduced by 20% cost.
Then, cost price of mobile phone = 8, 000 – 8, 000 x 20/100
= 8, 000 – 1, 600
= Rs. 6, 400

Again reduce 10% cost.
Then, price of mobile phone = 6, 400 – 6, 400 x 10/100
= 6, 400 – 640
= Rs. 5, 760

So, the final price of mobile phone is Rs. 5, 760.

Hence, correct answer is option (1) Rs. 5, 760.
