Answer:
ANSWER = ₹18.35
Step-by-step explanation:
A LABOURER ONE DAY EARNING = ₹125
OUT OF THIS, HE SPENT MONEY ON FOOD =
= 69 1/2 = 139/2
HE SPENT MONEY ON TEA = 20 3/4 = 83/4
HE SPENT MONEY ON OTHER EATABLES =
= 16 2/5 = 82/5
TOTAL MONEY USED IN EATABLES = 139/2+83/4+82/5
SO, TO MAKE THE DENOMINATOR SAME OF THE THREE FRACTIONS, WE HAVE TO ITS LCM.
LCM OF 2,4,5 IS 20.
= 139*10/2*10+83*5/4*5+82*4/5*4
= ₹(1390/20+415/20+328/20) = ₹2133/20 = ₹106.65
SAVINGS OF THAT DAY =
EARNING MONEY- SPENT MONEY
= ₹(125 - 106.65) = ₹18.35
SAVINGS OF THAT DAY IS ₹18.35
