      Solution

      Series I: (consecutive prime numbers X consecutive natural numbers) 374 + 11 x 2 = 396 396 + 13 x 3 = 435 435 + 17 x 4 = 503 503 + 19 x 5 = 598 598 + 23 x 6 = 736 374 should come in place of 370 So, 'P' = 370 Series II: 279 + (102┬а+ 12) = 279 + 101 = 380 380 + (82┬а+ 32) = 380 + 73 = 453 453 + (62┬а+ 52) = 453 + 61 = 514 514 + (42┬а+ 72) = 514 + 65 = 579 579 + (22┬а+ 92) = 579 + 85 = 664 514 should come in place of 510 So, 'R' = 510 Series III: 5940 ├╖ 4 = 1485 1485 ├╖ 4.5 = 330 330 ├╖ 5 = 66 66 ├╖ 5.5 = 12 12 ├╖ 6 = 2 66 should come in place of 60 So, 'Q' = 60
      [(R - P) ├╖ (Q - 32) x (P - 250)] ├╖ Q x P - 7R = [(510 - 370) ├╖ (60 - 32) x (370 - 250)] ├╖ 60 x 370 - 7 x 510 = [140 ├╖ 28 x 120] ├╖ 60 x 370 - 3,570 = [5 x 120] ├╖ 60 x 370 - 3,570 = 600 ├╖ 60 x 370 - 3,570 = 10 x 370 - 3,570 = 3,700 - 3,570 = 130
