Some equations are solved on the basis of a certain system. find the correct answer for the unsolved equation on the basis:
5 x 4 x 3 = 70,
6 x 5 x 4 = 140,
then 7 x 6 x 5 = ?
Options:
1. 210
2. 220
3. 230
4. 240
Answer: 4 (240)
5 x 4 x 3 = 60 + 10 = 70
6 x 5 x 4 = 120 + 20 = 140
7 x 6 x 5 = 210 + 30 = 240
5 x 4 x 3 = 70,
6 x 5 x 4 = 140,
then 7 x 6 x 5 = ?
