(122 - 82 ) of 52 + 52 = ?2
A man purchases some pens at a rate of 4 for ₹14 and an equal number at a rate of 5 for ₹18. He sells all the pens at a rate of 6 for ₹20. What is...

What will come in the place of question mark (?) in the given expression?
(3.2 × 35 + ?) ÷ √16 = 38.5
(2197)1/3 + (18)2 − 121 = ? − 69 × 5
45% of 360 - 160 + ? = √324
52% of 400 + √(?) = 60% of 600 - 25% of 400
4387897 – 3286871 – 51926 = ?
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2
