= 9. Ans
5. 36 − [18 − {14 − (15 − 4 ÷ 2 × 2)}]
Solution:
36 – [18 – {14 – (15 – 4 ÷ 2 × 2)}]
= 36 – [18 – {14 – (15 – 2 × 2)}]
= 36 – [18 – {14 – (15 – 4)}]
= 36 – [18 – {14 – 11}]
= 36 – [18 – 3]
= 36 – 15
= 21. Ans.
6. 27 − [18 − {16 − (5 − ¯4−1}]
Solution:
27 − [18 − {16 − (5 − ¯4−1}]
= 27 – [18 – {16 – (5 – 3)}]
= 27 – [18 – {16 – 2}]
= 27 – [18 – 14]
= 27 – 4
= 23. Ans.
7. 445 ÷ 35 of 5 + 45 × 310 − 15
Solution:
445 ÷ 35 of 5 + 45 × 310 − 15
= 245 ÷ 35 of 5 + 45 × 310 − 15
= 245 ÷31 + 45 × 310 − 15
= 2485 × 13 + 425 × 3105 − 15
= 85 + 625 − 15
= 40+6−525
= 46−525
= 4125
= 11625
8. (23+49) of 35 ÷ 123 × 114 − 13)
Solution:
(23+49) of 35 ÷ 123 × 114 − 13
= (23+49) of 35 ÷ 53 × 54 − 13
= (6+49) of 35 ÷ 53 × 54 − 13
= 109 of 35 ÷ 53 × 54 − 13
= 10293 of 35 ÷ 53 × 54 − 13
= 23 × 35 × 542 − 13
= 12 − 13
= 3−26
= 16
9. 713 ÷ 23 of 215 + 138 ÷ 234 − 112
Solution:
713 ÷ 23 of 215 + 138 ÷ 234 − 112
= 223 ÷ 23 of 115 + 118 ÷ 114 − 32
= 223 ÷ 2215 + 118 ÷ 114 − 32
= 223 × 1522 + 118 × 411 − 22
= 223 × 15522 + 1182 × 411 − 32
= 51 + 12 − 32
= 10+1−32
= 11−32
= 842
= 4
10. 517 − {3310 ÷ (245−710)}
Solution:
517 − {3310 ÷ (245−710)}
= 367 − {3310 ÷ (145−710)}
= 367 − {3310 ÷ (28−710)}
= 367 − {3310 ÷ 2110}
= 367 − { 331110 × 10 217}
= 367 − 117
= 36 −117
= 257
= 347
11. 934 ÷ [216 + {413−(112+134)}]
Solution:
394 ÷ [136 + {133−(32+ 74)}]
= 394 ÷ [136 + {133−(6+74)}]
= 394 ÷ [136 + {133−134}]
= 394 ÷ [136 + {52−3912}]
= 394 ÷ [136 + 1312]
= 394 ÷ [26+1312]
= 394 ÷ 3912

4110 − [212 −{56−(25+310−415)}]
= 4110 − [52 −{56−(25+310−415)}]
= 4110 − [52 −{56−(12+9−830)}]
= 4110 − [52 −{56−(21−830)}]
= 4110 − [52 −{56−1330}]
= 4110 − [52 −{25−1330}]
= 4110 − [52 − 1230]
= 4110 − [75−1230]
= 4110 − 6330

13. 156 + [223 − {334(345÷912)}]
Solution:
156 + [223 − {334(345÷912)}]
= 116 + [83 − {154(195÷ 192)}]
= 116 + [83 − {154(195× 219)}]
= 116 + [83 − {15342×25}]
= 116 + [83 − 32]
= 116 + [16−96]
= 116 + 76
= 11+76
