SOLUTIONS:
- (a) 1866242916= 432/54= 216/27
3216/27= 6/3= 2 (ans)
- (c) 7586 + 6532 + 458 +253 = 5624 + 8542 + ?
? = 663
- (c) 678976 = 824 (ans)
- (d) part of a year (365 days) is 36 hours and 30 minutes = 73/2
(73/2) / 36524 = 1/240 (ans)
- (a) 62 15 – 173 –2? = 19
2? = 27
So, ? = 7 (ans)
- (c) 4456976 = ?
? = 26 (ans)
- (b) 1478.4 56 + 66.8 57 = (?3) + (3434.5)
? = 887 (ans)
- (e) 1¼ +159158612= ?
5/4 +14/9*13/8*2/13 = 59/36 = 12336 (ans)
9.(b) 0.0640.47 =0.4?0.02562
(4/10)3(4/10)7= (4/10)x(4/10)8
(4/10)10= (4/10)x + 8
X + 8 = 10
X = 2 (ans)
- (b) 545+150+21=(?)2
441= (?)2
? = 441 (ans)
- (b) 72492=7?343
7274= 7? 73
6 = ? +3
? = 3 (ans)
- (d) 374 – 65– 1 = (?)3
(?)3= 3744 – 31= 343= 73
X = 3 (ans)
- (d) 6573 ÷ 21 × (0.2)2= ?
? =313.04 = 12.52 (ans)
14.(b) 74156 – ? – 321 – 20 + 520 = 69894
? = 74156 – 69894 + 179 = 4441 (ans)
15.(a) 40% of 265 + 35% of 180 = 50% of ?
⅖ 265 + 18035/100 = ? ½
? = 2(106 +63) = 338 (ans)
