Answer:
C. (iii) Rs. 52
D. (ii) 69
E. (ii) 6
Step-by-step explanation:
C. Let the amount that B gets be x
=> A will get x + 8
=> C will get x + 18
ATQ,
x + x + 8 + x + 18 = 158
=> 3x + 26 = 158
=> 3x = 132
=> x = 132/3
= 44
=> B gets Rs. 44
=> A gets Rs. 52
D. Let one of the angles be x
=> the other will be 180 - x
ATQ,
x - (180 - x) = 42
=> x + x = 42 + 180
=> 2x = 222
=> x = 111
=> The angles are 111 and 69
E. Let the number be x
ATQ,
x/4 - x/6 = 1/2
Multiplying the equation by 12
3x - 2x = 6
=> x = 6
