244.4.

Explanation:

Mental math:

Calculate 1% of 260="   "2.6

So 6% of 260=6timescolor(blue)"2."color(magenta)6
"                       "=(6timescolor(blue)2)+(6timescolor(magenta)0.6)
"                       "=12+3.6
"                       "=15.6

Then 94% of 260 is the whole 260, minus 6% of it:

94%times260=260-(6%times260)
"                    "=260-15.6
"                    "=244.4

All without the need for a calculator!
