BANK & INSURANCE (SIMPLIFICATION PERCENTAGE) Part 1

45% of 240 = 0.45 × 240 = 108

65% of 380 = 0.65 × 380 = 247

LHS = 108 + 247 = 355

13 × 9 = 117

355 = X + 117

X = 355 − 117 = 238

24% of 750 = 0.24 × 750 = 180

√169 = 13

√169 × 7 = 13 × 7 = 91

LHS = 180 + 91 = 271

256^(1/4) = 4 (because 4⁴ = 256)

271 = X + 4

X = 271 − 4 = 267

35% of 1840 = 0.35 × 1840 = 644

1938 ÷ 6 = 323

? × 19 + 323 − 78 = 644

? × 19 + 245 = 644

? × 19 = 644 − 245 = 399

? = 399 ÷ 19 = 21

29² = 841

17 × 7 = 119

40% of 3680 = 0.40 × 3680 = 1472

37.5% of 1472 = 0.375 × 1472 = 552

X = 841 + 119 − 552 = 408

27 × 13 = 351

351 + 45% of X = 513

0.45X = 513 − 351 = 162

X = 162 ÷ 0.45 = 360

8³ = 512

18 × 48 ÷ 27 = (864 ÷ 27) = 32

LHS = 512 + 32 = 544

12 × 13 = 156

14.28% of 280 ≈ 40 (since 14.285…% = 1/7 and 280 ÷ 7 = 40)

RHS (without X) = 156 + 40 = 196

544 = X + 196

X = 544 − 196 = 348

85% of 800 = 0.85 × 800 = 680

680 ÷ 17 = 40

(X ÷ 4 + 40) × 8 = 560

X ÷ 4 + 40 = 560 ÷ 8 = 70

X ÷ 4 = 70 − 40 = 30

X = 30 × 4 = 120

41² = 1681

39² = 1521

41² − 39² = 1681 − 1521 = 160

6.25 × 16 = 100

LHS = 160 + 100 = 260

X% of 400 = 260

X = (260 ÷ 400) × 100 = 65

1491 ÷ 7 × 3 = (1491 ÷ 7) × 3 = 213 × 3 = 639

19 × 8 = 152

(639 − 152) = 487

33% of 1600 = 0.33 × 1600 = 528

LHS = 487 + 528 = 1015

3⁵ = 243

1015 = X + 243

X = 1015 − 243 = 772

150% of 260 = 1.5 × 260 = 390

6.25% of 960 = 0.0625 × 960 = 60

LHS = 390 + 60 = 450

450 = X + 89

X = 450 − 89 = 361
