- Kid's tiffin price-30 and regular tiffin price is 24.
3/4 is for regular tiffin. so, 3/4*1440=1080.
No. of regular tiffin's =1080/24=45.
and No. of kid's tiffin =360/30=12.
if the price is reduced to 28(kid's tiffin) and 23(regular tiffin) then total money spend =28*12+45*23=1371.
so, 1440-1371=69. - 8 years agoHelpfull: Yes(56) No(7)
- CASE-1:- initial kid's tiffin and regular tiffin price is 30 and 24
and already mention amount 1-3/4 is for regular tiffin, amount spend by caterer is 1440.................1
1/4*1440=360
now, Number of regular tiffin is 360/30=12
now for kid's tiffin 1440-360=1080
now, Number of kid's tiffin is 1080/24=36
CASE-2;- TOTAL after change is 12*28+36*23=1353.................................................................2
form 1 and 2
1440-1353=87

- 69 is right. There is no option for it.
- 8 years agoHelpfull: Yes(4) No(1)
- total caterer spend=1440
for regular tiffin=(3/4)*1440=360
for kids tiffin=1080
no of kids tiffin in a month=1080/30=36
no. of regular tiffin in a month=360/30=12
total spend in both the tiffin from new price=(36*28)+(12*23)=1284
therefore total savings=1440-1284=156
