1.
Sum of first 'n' natural numbers is = n(n+1)/2
Total money is 1 + 2 + 3 +... + 30 = (30 x 31) / 2 = Rs. 465
2.
Number is = 76 Q + 26, where Q is the Quotient and will have values 1, 2, 3 etc..,
= 19 x 4 x Q + 19 x 1 + 7
When the number is divided by 19, the remainder will be 7
Shortcut : When the second divisor is a factor of first divisor, answer is obtained by dividing the first remainder by the second divisor. Here divide 26 by 19, the remainder is 7.
3.
LCM of 6 and 7 is 42. Divide 6869 by 42, the remainder is 23.
So, Required number is (42 - 23) = 19
4.
Dividing the power 438 by 4, the remainder is 2.
(36527)438 will also have the same digit in the unit place as (36527)2
The digit in the unit place of (36527)2 is 9.
So, the digit in the unit place of (36527)438 is 9.
5.
Let the third number be "X". Then first number will be 2X and the second number will be 4X.
So, 2X + 4X + X = 126 => X = 18
Second number is 4 x 8 = 72
6.
Let the two digit number be 10X + y
so, 10X + y - (10Y + X) = 27
=> 9X - 9Y = 27 => X - Y = 3
So, Difference between the digits of the number is 3
7.
To divide a number by 72, it should be completely divisible by both 8 and 9.
6 + 2 + 7 + 3 + 5 + 9 + 7 + 2 = 41
The number, which is divisible by 9 after 41 is 45. 45-41 = 4 If we keep 4 in place of '#' symbol it is divisible by 9. also we have to check up whether it is divisible by 8, as the last 3 digits are divisible by 8, it is divisible by 8 also.
So, 4 should come in place of '#'
Set 1
1.
(1.87 x 1.87 x 1.87 + 0.13 x 0.13 x 0.13) / (1.87 x 1.87 + 0.13 x 0.13 - 0.13 x 1.87) = ?
This is like in the form of a3+ b3
(a + b) (a2- ab + b2)
So, answer is 1.87 + 0.13 = 2
2.
5(1/4) + 2(2/7) - 3(1/6) - 4(1/4) = ?
(1/4) + (2/7) - (1/6) - (1/4) = 5/42
3.
(18/100) x 1220 + (35/100) x 2750
=> 219.6 + 962.5 = 1182.1
5.
(16)1/2 + (√7 x √7 x √7)1/3+ (23)2= ?3+√7+21
=> 4 + √7 + 529 = ?3+ √7+21
?3 = 512 => ? = 8
6.
( √?- 1)2 = 8 - √28
= ( √?- 1)2 = 7 + 1 - 2√7
=> ( √?- 1)2 = ( √7- 1)2
=> √? = √7
=> ? = 7
7.
1755 % 27 % 5 = 2 x √?
=> (1755 / (27 x 5)) = 2 x √?
=> √? = 13/2 = 6.5
=> ? = 42.25
8.
(0.6)2 % (0.216)2 = (0.6)? % (0.36)3
(0.6)2 / (0.6)3 = (0.6) ? / ((0.6)2 )3
= (0.6) ? / (0.6)6
=> (0.6) 2-3 / (0.6)?-6
=> 2-3 = ? - 6
=> ? = 5
Set 2
1.
5 (1/8) x (8/9) % 2(1/21) x 7(1/13) = ?
5 x 1 % 2 x 7 = ?
=> ? = (5/2) x 7 = 17.5
2.
94.98% of 1299 - 12.49% of 1839.97 = ?
=> 95% of 1300 - 12.5% of 1840
=> 1235 - 230 = 1005
3.
13.604 x 21.009 x 18.971 = ?
13.6 x 21 x 19 = 5426.4
4.
17.978 - 21.008 + 32.981 - 12.968
= ? - 17.001
=> 18 - 21 + 33 - 13 + 17 = ?
=> ? = 34
5.
(249 /15) x (399 / 19) % (14 / 199)
=> (250 /15) x (400 /20) x (200/15)
