Which two numbers (not digits) should be interchanged to make the given equation correct?

Given equation:

$15 + 5 \times 8 - 72 \div 4 + 16 \times 3 = 101$

Step 1: Solve original (BODMAS)

$5 \times 8 = 40$
$72 \div 4 = 18$
$16 \times 3 = 48$

So,
$15 + 40 - 18 + 48 = 85 \neq 101$

Step 2: Check options

🔸 Interchange 5 and 3

New equation:
$15 + 3 \times 8 - 72 \div 4 + 16 \times 5$

Now solve:

$3 \times 8 = 24$
$72 \div 4 = 18$
$16 \times 5 = 80$

So,
$15 + 24 - 18 + 80 = 101$ ✅

Final Answer:

5 and 3 / 5 और 3
