Solution:
1). B)? = √2209 + √361 – √1296
= 47 + 19 – 36 = 30

2). C) ? ={ [8 /(10×100)] × 3072 } + [(12/100) x785] = 24.576 + 94.20 = 118.776

3). B) (16)21-? = 166.5x 1612.25
or, (16)21-? = (16)6.5+12.25
or, 21 – ? = 18.75
or, ? = 2.25

4). D)272.5 × ((243)3)? = 323.5
or, (33)2.5 × ((35)3)? = 323.5
or, 33×2.5× 35×3×?= 323.5
or 15×? = 23.5 – 7.5 = 16
? = 16 /15 = 1.0667

5). A)? = 3√175616 × √1936 + (36)2
56 × 44 + 1296 = 2464 + 1296 = 3760

6). A)? = [(4.15/100) × 1400] + [(3.2/100) × 1600] + (361)1/2
= 58.1 + 51.2 + 19
= 128.3

7). D)(19/3) + (21/5) + (10/7) – (15/7) + (22/5) × (10/3)
= (19/3) + (21/5) + (10/7) – (15/7) + (44/3) = [(19+44) / 3] + [(10 – 15) / 7] + (21/5)
= (63/3) + (-5/7) + (21/5) = 21 – (5/7) + (21/5)
= (735 – 25 + 147) / 35 = 857 / 35 = 24 17/35

8). B).(56)? = (8)4.2 × 84.2× 78.4× (56)4.3
= (88.4× 78.4) × (56)4.3 = (56)8.4 × (56)4.3
= (56)(8.4+4.3)= (56)12.7
? = 12.7

9). D)√33124 × √2601− 832 = ?2 + 372
= 182 x 51 – 6889 = ?2 + 1369
= 2393=?2 + 1369
= ?2 = 2393 −1369 =1024
? = √1024 = 32


10). B)
