Answers & Solutions:

1) Answer (A)

3463 × 295 = 1021585
1021585 – 18611 = 1002974
1002974 – 5883 = 997091

2) Answer (C)

(23.1)$^{2}$ = 533.61
(48.6 )$^{2}$ = 2361.96
(39.8)$^{2}$ = 1584.04
533.61 + 2361.96 – 1584.04 = 1311.53
1311.53 – 1147.69 = 163.84

3) Answer (D)

We solve the problem as per BODMAS rule
$\frac{195}{308}$ ÷ $\frac{39}{44}$ = $\frac{5}{7}$
$\frac{28}{65}$ x $\frac{5}{7}$ = $\frac{4}{13}$
$\frac{4}{13}$ + $\frac{5}{26}$ = $\frac{13}{26}$ = $\frac{1}{2}$

4) Answer (C)

[ $\sqrt{8}$ (3 +1) x $\sqrt{8}$(8 + 7)] – 98
= [4$\sqrt{8}$ x 15 x $\sqrt{8}$ ] – 98
= [60 x $\sqrt{8}$] – 98
= 480 – 98 = 382

5) Answer (B)

$\sqrt{11449}$ x $\sqrt{6241}$ – (54)² – (74)² = $\sqrt{?}$
$\sqrt{?}$ = [107 x 79] – 2916 – 5476
= 8453 – 2916 – 5476 = 61
$\sqrt{?}$= (61)² = 3721

6) Answer (C)

40 x $\frac{4330}{100}$ + 59 + $\frac{5000}{100}$
= 1732 + 2950
= 4682

7) Answer (E)

$\frac{43931}{2111}$ x 401 = 8345.01 ≈ 8300

8) Answer (B)

After taking approximation equation will be

$\sqrt{6354}$ x 34.993 = 80 x 35 = 2800

9) Answer (E)

$\sqrt[3]{4663}$ ≈ 17
17 + 349 = ? ÷ 21
366 x 21 = ?
? = 7686 ≈ 7680

10) Answer (C)

After taking approximation equation will be 60 ÷ 12 x 6 = 30
