X = small van capacity, y = larger van capacity
y = x + 6
2x + y = 57
now we sub in x + 6 for y
2x + x + 6 = 57
3x + 6 = 57
3x = 57 - 6
3x = 51
x = 51/3
x = 17
y = x + 6
y = 17 + 6
y = 23
small van (x) has 17 seats and large van (y) has 23 seats

Answer:


Step-by-step explanation:
Let Cost price ( C.P ) be x
<u>Finding </u><u>the </u><u>Marked </u><u>price </u><u>and </u><u>selling </u><u>price </u>
Marked price = 
⇒
⇒
⇒
⇒ ( i )
Selling price = 
⇒
⇒
⇒
⇒
⇒
⇒ ( ii )
<u>Finding </u><u>the </u><u>value </u><u>of </u><u>x </u><u>(</u><u> </u><u>Cost </u><u>price </u><u>)</u>

⇒
⇒

⇒
⇒
Value of x ( cost price ) = Rs 1250
<u>Now</u><u>,</u><u> </u><u>Replacing </u><u>the </u><u>value </u><u>of </u><u>x </u><u>in </u><u>(</u><u> </u><u>i </u><u>)</u><u> </u><u>in </u><u>order </u><u>to </u><u>find </u><u>the </u><u>value </u><u>of </u><u>marked </u><u>price</u>

⇒
<u>Replacing </u><u>value </u><u>of </u><u>x </u><u>in </u><u>(</u><u> </u><u>ii </u><u>)</u><u> </u><u>in </u><u>order </u><u>to </u><u>find </u><u>the </u><u>value </u><u>of </u><u>selling </u><u>price</u>

⇒
⇒
Thus , Marked price of the fan = Rs 1500
Selling price of the fan = Rs 1230
Hope I helped!

1) 4a/5
a% of 80 = a% (80) = (a/100)(80) = 80a/100 = 4a/5
2) 17b/100 or 0.17b
17% of b = (17/100)(b) = 17b/100 [ = 0.17b ]
3) ab/100
a% of b = (a/100)(b) = ab/100
