• A. 12$
• B. 17$
• C. 26$
• D. 52$

Answer 1

The correct option is B 17$LetChaayossold$x$no.ofbananashakeand$(40-x)$ no.of mango shake .

Then according to the question,

$\Rightarrow 2\left(x\right)+2.50(40-x)=87$

$\Rightarrow 2x+100-2.50x=87$

$\Rightarrow 2x-2.50x=87-100$

$\Rightarrow .50x=13$

$\Rightarrow x=\frac{13}{0.50}=26$

No. of banana shake he sold is $26$

$\therefore$No. of mango shake=$40-26=14$

Cost of one banana shake=$2

$\therefore$ cost of $26$ banana is $=26\times 2=$52$

Cost of one mango shake=$2.50

$\therefore$ cost of $14$ banana shake$=14\times 2.50=$35$

Money he make on the banana shake than mangoshake=52-$35=$17$
