Question : 40 of 100

Marks: +1, -0

If -3%1 = 3, 3%6 = -18 and -7%4 = 28, then find the value of -2%9 = ?

Solution:

Given : -3%1 = 3, 3%6 = -18 and -7%4 = 28
If we replace '%' with and multiply the product with '-1', then we will get the desired result.
Eg :-

(−3 × 1) × (−1) = 3

and

(3 × 6) × (−1) = −18

and

(−7 × 4) × (−1) = 28

Similarly,

(−2 × 9) × (−1) = 18
