In a city 80 percent speaks English 70 percent speaks Hindi and 10 percent do not speak both It was found that 162 people talk both How many are there in the city?

Answer:
I think this is right. Because 10% do not speak both, 162 must equal 90% of the city. 10% is therefore a 9th of 162 which is 18. Therefore there are 162 + 18 in the village. 180
