Answer:

- 1210

Step-by-step explanation:

According to BODMAS / PEMDAS rule, we will do multiplication first and then subtraction . So -23 * 56 = -1288 and then the subtraction , 78 + (-1288) =78-1288= -1210

The fraction should be -1210 / 1

36 men can compete a piece of work in 18 days in how many days will 27 men compete the same work​
Drupady [299]

Step-by-step explanation:

Explanation:

Less Men, means more Days {Indirect Proportion}

Let the number of days be x then,

27 : 36 :: 18 : x

[Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]

=>27x = 36 * 18

=> x = 24

So 24 days will be required to get work done by 27 men..
