Options

A

₹23440

₹23440

B

₹26420

₹26420

C

₹22140

₹22140

D

₹24480

₹24480


Solution:

Correct Answer:

C

₹22140

₹22140


Let's Raju's total income = 100x

expenditure on transport = 10% of 100x = 10x

expenditure on food = 20% of 100x = 20x

expenditure on clothing = 30% of 70x = 21x

Savings of Raju = 100x - 51x = 49x = 26460

x = 540

Now total expenditure on food and clothing = 20x + 21x = 41x = 41 ×\times 540 = ₹22140

 

माना की राजू  की कुल आय = 100x

यातायात पर खर्च  = 10% of 100x = 10x

भोजन  पर खर्च = 20% of 100x = 20x

कपड़ों  पर खर्च = 30% of 70x = 21x

राजू की कुल बचत  = 100x - 51x = 49x = 26460

x = 540

अब भोजन तथा कपड़ों पर कुल खर्च = 20x + 21x = 41x = 41 ×\times 540 = ₹22140
