Question: `5005 - 500 ÷ 10.00 = ?`
A
`0.5`

B
`50`

C
`5000`

D
`4505`

Note: Given Exp, `= 5005 - 500 ÷ 10` `= 5005 - 500` `= 4505`

Question: On simplifaction, the expression `1-[1 - {1 - (1 - 1 - 1)}]`yields.
A
`0`

B
`1`

C
`2`

D
`3`

Note: Given Exp, `= 1 -[1 - {1 - (1 - bar1 - 1)}]` `= 1 - [1 - {1 - (1 - 0)}]` `= 1 - [1 - {1 - 1}]` `= 1 - [1 - 0]` `= (1 - 1)` `= 0`

Question: How many pieces of `0.85` metres can be cut from a rod `42.5`metres long .
A
`30`

B
`40`

C
`60`

D
None of these

Note: Number of pieces , `= 42.5/0.85` `= 42.50/0.85` `= 4250/85` `= 50`

Question: `b - [b - (a + b) - {b - (b - a - b)} + 2a]`
A
`2b`

B
`a - b`

C
`a + b`

D
None of these

Note: Given Exp , `= b - [b - (a + b) - {b - {b - bara - b)} + 2a]` `= b - [b -a - b - {b - (b - a + b)} + 2a]` `= b - [-a - {b - 2b + a + 2a}]` `= b - [- a - {- b + 3a}]` `= b - [ -a + b - 3a]` `= b - [- 4a + b]` `= b + 4a -b` `= 4a`.

Question: `31/10 xx 3/10 + 7/5 ÷ 20 = ?`
A
`0`

B
`1`

C
`100`

D
`107/200`

Note: Given Exp, `= 31/10 xx 3/10 + 7/5 xx 1/20` `= (93/100 + 7/100)` `= 100/100` `= 1`.

Question: `(16 - 6 xx 2 + 3)/(23 - 3 xx 2) = ?`
A
`7/17`

B
`23/40`

C
`14/23`

D
`2/17`

Note: Given Exp , `= (16 - 12 + 3)/(23 - 6)` `= 7/17`

Question: `((272 - 32)(124 + 176))/(17 xx 15 - 15)=?`
A
`0`

B
`2.25`

C
`300`

D
None of these

Note: Given Exp , `= (240 xx 300)/(255 - 15)` `= (240 xx 300)/(240)` `= 300`.

Question: `1/ (2 1/3) + 1/ (1 3/4)` is equal to :
A
`4 1/12`

B
`7/14`

C
`12/49`

D
None of these

Note: Given Exp , `= 1/((7∕3)) + 1/((7∕4))` `= (3/7 + 4/7)` `= 7/7` `= 1`.
