## MIND-Xpander maths problems

**PUZZLE A**

The second of five consecutive multiples of 11 is removed. The other four are then added together to give 715. What is the lowest multiple of the remaining four? There are two possible solutions.

**Solution one**

Let x be the unknown multiplier to the multiples.

11x + 0 + 33x + 44x + 55x = 715

143x = 715

x = 5 Checking: 55 + 0 + 165 + 220 + 275 = 715

**Solution two**

Let x be the lowest multiple multiplier.

11(x) + 0 + 11(x+2) + 11(x+3) + 11(x+4) = 715

11x + 0 + (11x + 22) + (11x + 33) + (11x + 44) = 715

44x + 99 = 715

44x = 616

x = 14

Checking: 154 + 0 + 176 + 187 + 198 = 715

**PUZZLE B**

Simplify the following expression: √5 x √15 x √10

**Solution**
