Question

(i) A number when increased by 23% becomes 861 ; find the number. (ii) A number when decreased

Answer 1

Answer:

(i) The answer is 700.

Step-by-step explanation:

Based on the given values, we could formulate an equation, which is:

x * 1.23 = 861

We got 1.23 because "a number (100%), when increased by 23%, becomes 861 (123%)". We simply convert 123% to decimal form.

Next step is to divide both sides by 1.23, so that all that will remain in the left side of the equation is x.

x = 861/1.23

x = 700

There you go!
