Answer
Q-(1) Sol-(5)
30% of 4450 + 60% of 350 = ?
1335 + 210 = ?
? = 1545
Q-(2) Sol-(5)
? = 57.5 + 225 .35
= 282.85
Q-(3) Sol-(2)
? =7752/2584 = 3
Q-(4) Sol-(2)
855.45 +265.102+ 584.321 – 520.234 = ?
? = 1184.639
Q-(5) Sol-(3)
?=4290–448=3842
Q-(6) Sol-(2)
Let first part is x and second part is y ;
x : y = 2 : 7
9 → 82800
1 ? 9200
x = 2 → 18400
Q-(7) Sol-(4)
Cost price of the table : cost price of chair = 3 : 2
let the cost price of table = 300
and the cost price of chair = 200
according to question,
total profit = 3 × 10 - 2 × 8 = 14
14 % = 210
1% = 15
300% = 4500
Q-(8) Sol-(4)
Required answer=55
Q-(9) Sol-(2)
2x +3x + 7x = 540×3
12x = 1620
x = 135
A = 270 B = 405 C = 945
According to question
324+ 283.5 + x = 3×630
x = 1282.5
Increase in C = 36% (approx)
Q-(10) Sol-(5)
let the breadth of the plot is x meter
so length of the plot will be = x + 6
so area of the plot will be equal to x × ( x +6 )
length of the lawn is = x + 6 meter
breadth of the lawn is = 6 meter
so , according to question,
x×(x+6)– (x+6) 6 = 864
x2 + 6x–6x–36 = 864
x2 = 900
x = 30
b= 30 l = 36
Area of the plot is = 30 × 36 = 1080 m2
