D. 3200

E.None of these**D. 3200**

**Explanation:**

Let there are X books in the library.

Hindi books = 60% of X = 60X /100 = 0.6X

Remaining Books = X – 0.6X = 0.4X

English books = 40% of reaming books = 60% of 0.4X = 0.24X.

Malayalam Books = X-0.6X -0.24X = 0.16X

Given,

0.24X = 4800

X = 4800/0.24 = 20000

Malayalam Books = 0.16X = 0.16*20000 = 3200.**80% of a small number is 4 less than 40% of a larger number. The larger number is 125 greater than the smaller one. The sum of these two numbers is**

A. 325

B. 345

C. 355

D. 365

E. None of these**C. 355**

**Explanation:**

smaller number = x; larger number = y

0.8x + 4 = 0.4y

4y – 8x = 40

y – x = 125

x = 115; y = 240

x + y = 355**In a private company 60% of the employees are men and 48% of the employees are Engineer and 66.6% of Engineers are men. The percentage of women who are not engineers is?**

Women who are Engineers = 160x

Women who are not Engineers = 400x – 160x = 240x

Required percentage = 240/400 * 100 = 60%**Initially, Suresh has Rs.200 in his paytm wallet then he increased it by 20%. Once again he increased his amount by 25%. The final value of money in his wallet will be how much % greater than the initial amount?**

After increasing in cost of fresh mangoes 30%,

Cost of fresh mangoes = 130

And cost of packing go down by 50 % so,

Cost of packing = 10.
