Firstly, Rs. 10/12=0.83
Since cost price of each flower = Rs. 0.83
And, Selling price of each flower = Rs 1.50
Finding total cost of 240 flowers= 0.83*240= Rs.199.2
And selling price of 240 = 1.5*240= Rs 360
Finding profit=
selling price-cost price=profit
360-199.2=160.8
He made a profit of Rs 160.8
finding profit pecent=
profit*100/C.P
160.8*100/199.2
80.72%
Hence, he made 80.72% profit

Your answer is wrong as you chop off the decimal digits of 10/12. Its better to keep it in Fractional form and proceed to the solution. The answer will be sharp 80%.

Cost of 1 dozen(12 pieces) roses = Rs. 10
Then cost of 1 piece rose = Rs. 10/12
And cost of 240 roses will be Rs. (240*10/12) = Rs. 200
Hence the cost price(C.P) of roses = 200
He sold 1 rose at the rate of 1.50
Then the selling price of 240 roses = Rs. (240 * 1.50) = 360
Hence the Selling price(S.P) of roses is Rs. 360
Here we can see that S.P>C.P
Therefore Their is profit of S.P - C.P = 360 - 200 = Rs 160

And the profit percentage will be = (Profit/C.P *100) %
=>160/200 * 100 = 80%
