What value should come in place of question mark(?) in the question?
\(6{2\over3} + {6\over7} + {7\over3} = ?\)
What value should come in place of question mark(?) in the question?
\(6{2\over3} + {6\over7} + {7\over3} = ?\)
Correct Answer – Option 3 : 69/7
Given:
\(6{2\over3} + {6\over7} + {7\over3} = ?\)
Calculations:
Solving the given fraction,
⇒ {[(6 × 3) + 2]/3} + (6/7) + (7/3)
⇒ [(18 + 2)/3] + (18/21) + (49/21)
⇒ [(20 × 7)/21] + (67/21)
⇒ (140/21) + (67/21)
⇒ 207/21
⇒ 69/7
∴ 69/7 will replace the question mark in the question
What value should come in place of question mark(?) in the question?
[(130)2 ÷ 25 × 15] ÷ 30 = ?
What value should come in place of question mark(?) in the question?
[(130)2 ÷ 25 × 15] ÷ 30 = ?
Correct Answer – Option 1 : 1193
Given:
83 ÷ 24 + 52 × 72 – (22)3 = ?
Concept used:
ax/ay = ax – y
(ax)y = ax × y
ax × bx = (a × b)x
Calculations:
Using the given concept to solve the equation,
⇒ [(23)3 ÷ 24] + (5 × 7)2 – 43
⇒ (29/24) + 352 – 64
⇒ 25 + 1225 – 64
⇒ 32 + 1225 – 64
⇒ 1225 – 32
⇒ 1193
∴ 1193 will replace the question mark in the given question
