Explanation:

Let CP of chair be x and CP of stools be y,
According to question,
4x+9y = 1340 ….. (i)
10%of 4x + 20% of 9y = 188 => 4x + 18 y = 1880 …… (ii)
Solving the equation (i) and (ii) by elimination method, we get
y = 60
Putting the value of y in equation (i), we get
4x = 800,
Thus, the money paid for the chair be Rs. 800
Hence option (3)
